One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, such as the rate of change in the concentration of reactants or products with time. 51166-71-3, Name is 2,6-Di-O-methyl-β-cyclodextrin, formurla is C56H98O35. In a document, author is Prasad, R. L., introducing its new discovery. Recommanded Product: 51166-71-3.

ENERGETICS AND STRUCTURAL INSIGHTS OF MOLECULAR CONDUCTORS USING DENSITY FUNCTIONAL THEORY METHODS: 1,3-DITHIOLE-2-THIONE, 1,3-DITHIOLE-2-ONE, 1,3-DIOXOLE-2-ONE, AND 1,3-DIOXOLE-2-THIONE

Computations were carried out employing the restricted Hartree-Fock (RHF) and density functional theory (DFT) methods to investigate the geometries and energies for the 1,3-dithiole-2-thione (DTT), 1,3-dithiole-2-one (DTO), 1,3-dioxole-2-thione (DOT), and 1,3-dioxole-2-one (DOO) molecules and their radical cations. The geometrical parameters of all the four molecules suggest a finite extent of extended conjugation across the molecules. The radical cations of the DTT and DOT molecules exhibit increased extent of conjugation compared to their neutral analogues. However, on going from the neutral DOO and DTO molecules to their radical cations, the extent of conjugation across the ions decreases and two unsaturated sites become isolated from each other. Requirement of the relaxation energy for the formation of radical cation is much lower for the DTT and DOT molecules compared to that for the DOO and DTO molecules. Smaller relaxation energy requirement favors minimal resistance to charge transport along the molecular stacking. Therefore, it is speculated that the DTT and DOT molecules are better molecular conductors as compared to the DOO and DTO molecules.

Naphthodioxinone-1,3-benzodioxole as Photochemically Masked One-Component Type II Photoinitiator for Free Radical Polymerization

A 1,3-benzodioxole derivative of naphthodioxinone, namely 2-(benzo[d][1,3]dioxol-5-yl)-9-hydroxy-2-phenyl-4H-naphtho[2,3-d][1,3]dioxin-4-one was synthesized and characterized. Its capability to act as caged one-component Type II photoinitiator for free radical polymerization was examined. Upon irradiation, this photoinitiator releases 5-benzoyl-1,3-benzodioxole possessing both benzophenone and 1,3-dioxole groups in the structure as light absorbing and hydrogen donating sites, respectively. Subsequent photoexcitation of the benzophenone chromophore followed by hydrogen abstraction generates radicals capable of initiating free radical polymerization of appropriate monomers.

Ab initio determination of geometries and vibrational characteristics of building blocks of organic super-conductors: TTF and its derivatives

Molecular behavior of the building block ([2-(1,3-dithiole-2-ylidene)-1,3-dithiole] =tetrathiafulvalene (TTF)} of organic superconductors have been investigated along with its three derivatives, namely, {[2-(1,3-dioxole-2-ylidene)-1,3-dioxole] tetraoxafulvalene (TOF)}; [2,2]-bi-[[1,3] oxathiolylidene]=Der I and 2-(3H-Furan-2-ylidene)-[1,3] oxathiole=Der II. The properties of the molecules such as molecular geometries, frontier MOs and vibrational spectra have been investigated by using DFT method at the B3LYP level employing 6-311++G(d,p) basis set. The geometrical parameters and atomic charges on various atomic sites of the TTF, TOF, Ders land II suggest extended conjugation in these systems. The present calculations lead to the reassignments for of some of the fundamentals and new interpretations for some of the observed IR and Raman frequencies. One of the two modes involved in the Fermi resonance giving rise to the doublet 1555 and 1564 cm(-1) needed to be revised and another doublet 3083 and 3108 cm(-1) could be interpreted as a Fermi resonance doublet. Out of the two nu(C=C) modes under the a(1) species, the lower frequency mode is assigned to the nu(C=C) of the ring and the higher one to the nu(C=C) of the central C=C bond contrary to the assignment reported in literature. The conducting properties of these molecules depend mainly on this mode. (C) 2012 Elsevier B.V. All rights reserved.

Intramolecular Diels-Alder cycloadditions of cis-cyclohexadienediols derived enzymatically from (2-azidoethyl)benzene. Construction of highly functionalized bridged isoquinoline synthons

(3aR,7aS)-4-(2-Azidoethyl)-2,2-dimethyl-3a,7a-dihydrobenzo[1,3]dioxole (22) was converted in two steps to trienes 23 and 24, which upon heating underwent intramolecular Diels-Alder reactions to give mixtures of isomeric 11,11-dimethyl-5-oxo-10,12-dioxa-4-azatetracyclo[6.5.2.0(1.6).0(9,13)]pentadec-14-ene-7-carboxylates 25, 26 and 27, 28, respectively. These products were separated and identified. For comparison, intermolecular Diels-Alder cycloaddition of diene 22 with maleic anhydride was carried out. Products of this reaction, 1-(2-azidoethyl)-4,4-dimethyl-3,5,10-trioxatetracyclo[5.5.2.0(2,6).0(8,12)]tetradec-13-ene-9,11-diones (29 and 30) were converted to methyl ester analogues of 31 and 32 in a two-step sequence. The stereochemical outcome of these cycloadditions is discussed as well as their possible utilization in organic synthesis, especially in total synthesis of some alkaloids.

N’-(2-((4-(Benzo[d][1, 3]dioxol-5-yl)-3-cyano-6-(naphthalen-2-yl)-pyridin-2-yl)oxy)- acetyl)benzohydrazide (6) and hydrazide derivatives (7-10) were synthesized via reaction of 3-cyano-pyridinacetohydrazide (5) with benzoylchloride and the appropriate aldehyde, respectively. Also, 4-(Benzo[d][1, 3]dioxol-5-yl)-2-(2-(3-methyl-5-oxo-4,5-dihydro-1H-pyrazol-1-yl)-2-oxoethoxy)-6-(naphthalen-2-yl) nicotinonitrile (11) was prepared through reaction of (5) with ethylacetoacetate. In addition, the hydrazide 5 was used as a starting material for synthesizing other nicotinonitrile derivatives (12, 13) and acetohydrazides (14, 15). Moreover, new 2, 5-disubsitituted-1,3,4-oxadiazoles (16, 17) were furnished by the reaction of (5) with benzoic acid derivatives. The cytotoxicity for some new compounds was investigated against human breast cancer MCF-7 and MDA-MB-231 cell lines at concentrations (0, 10, 20, 40, 60, 80, and 100 mu g/ml) using MTT assay. Compounds (4, 9, 14 and 17) were recorded the lowest half-maximal inhibitory concentrations (IC50s) against MCF-7 and MDA-MB-231 cell lines via cytotoxicity assays. These results were confirmed using molecular docking experiments. From the previous observations, we suggested that our synthesized compounds could be of great potential against breast cancer cells.

Collagen modified with epoxidized safrole for improving antibacterial activity

An epoxidized safrole, 5-(oxiran-2-ylmethyl)-benzo[d][1,3] dioxole (OYBD), was synthesized and employed to modify collagen for improving its antibacterial activity. The interaction between collagen and OYBD, and the structure/properties of the modified collagen were investigated in detail. The results indicated that the OYBD-modified collagen showed a higher de-nature temperature (Td, 90.2 degrees C), improved hydrophobic properties (contact angle from 84.2 degrees to 89.1 degrees) and enhanced tensile strength (6.2-11.0%) without destroying its triple helix structure. From observation of scanning electron microscopy (SEM), a higher density of intertwining morphology and a more stable network structure were observed, which was consistent with improved tensile strength and reduced breaking extension stress. The antibacterial test and LIVE/DEAD Baclight bacterial viability assay illustrated that the modified collagen exhibited excellent antibacterial activity to both Gram-negative and Gram-positive bacteria. Furthermore, the OYBD-modified collagen still exhibited cytocompatibility, supporting human fibroblast proliferation, which holds a great potential for developing antibacterial collagen-based biomaterials.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 526-95-4, in my other articles.
