Polyoxyethylene-polyamide multiblock copolymers were successfully synthesized from α,ω-poly(oxyethylene)dicarboxylic acid (I), a mixture of two dicarboxylic acids, and an aromatic diisocyanate by 2 synthetic routes, i.e., one-step and two-step methods. In the two-step method, α,ω-diisocyanate-terminated polyamide oligomers, preformed from a mixture of isophthalic acid (II) and azelaic acid (III) with 4,4′-MDI, were reacted with I to form multiblock copolymers. In the one-step method, the reaction components, MDI, II, III, and I, were reacted all together. These polymerizations were carried out in the presence of 3-methyl-1-phenyl-2-phospholene 1-oxide as a catalyst in tetramethylene sulfone, giving multiblock copolymers with inherent viscosities of 0.5-1.1 dL/g. The copolymers were soluble in amide-type solvents, and transparent, ductile, and elastomeric films could be cast from their N,N-dimethylacetamide solutions The tensile strength and modulus of the films thus prepared decreased with an increase in the polyoxyethylene content, whereas the elongation at break increased. The tensile strength, elongation at break, and tensile modulus of the multiblock copolymer films ranged from 47 MPa, 160%, and 1.1 GPa, resp., to 15 MPa, 880%, and 12 MPa, resp.

Name: 4-Methyl-1-phenyl-2,3-dihydro-1H-phosphole 1-oxide. Aromatic compounds can be divided into two categories: single heterocycles and fused heterocycles. Compound: 4-Methyl-1-phenyl-2,3-dihydro-1H-phosphole 1-oxide, is researched, Molecular C11H13OP, CAS is 707-61-9, about Organocatalyzed Reduction of Tertiary Phosphine Oxides. Author is Schirmer, Marie-Luis; Jopp, Stefan; Holz, Jens; Spannenberg, Anke; Werner, Thomas.

A novel selective catalytic reduction method of tertiary phosphine oxides to the corresponding phosphines has been developed. Notably, the reaction proceeds smoothly with low catalyst loadings of 1-5 mol% even at low temperature (70°). Under the optimized conditions various phosphine oxides could be selectively reduced and the desired phosphines were usually obtained in excellent yields above 90%. Furthermore, authors have developed a one-pot reaction sequence for the preparation of valuable phosphine·borane adducts. Simple addition of BH3·THF subsequent to the reduction step gave the desired adducts in yields up to 99%.

In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Catalytic transformation of silicon tetraisocyanate Si(NCO)4 to a polymeric silylcarbodiimide, published in 2013, which mentions a compound: 707-61-9, Name is 4-Methyl-1-phenyl-2,3-dihydro-1H-phosphole 1-oxide, Molecular C11H13OP, Formula: C11H13OP.

A new way for the preparation of inorganic polymeric carbodiimide-based networks is presented which resembles the transformation of mol. isocyanates using 1-phenyl-3-methyl-2-phospholene-1-oxide as a catalyst. The resp. reaction sequence, well established in preparative organic chem., has been applied for the synthesis of carbodiimide-based SiNC(O) materials. Starting from Si(NCO)4 (silicon tetraisocyanate), a transformation to an insoluble extended inorganic array was achieved in boiling dodecane (T = 216 °C). Anal. of the polymer using X-ray diffraction, FT-IR, d. measurement, matrix-assisted laser desorption/ionization time of flight and TGA revealed that this highly moisture-sensitive amorphous network consists of oligomers of high molar mass and exhibits a high d. of around 1.5 g.cm-3, which corresponds quite well to the calculated d. of crystalline Si(NCN)2 reported in the literature. Degradation of this ‘SiNC(O) phase’ with the release of N2 and (CN)2 finally provided SiC as the only crystalline product. No indication of the formation of crystalline Si3N4 or intermediate crystalline ‘SiC2N4’, silicon carbodiimide (= Si(NCN)2), was noticed. Copyright © 2012 John Wiley & Sons, Ltd.

3-Methyl-1-phenyl-2-phospholene and 1-phenyl-2-phospholene 1-oxides were converted into 2-bromo-3-hydroxy-3-methyl-1-phenylphospholane and 2-bromo-3-hydroxy-1-phenylphospholane 1-oxide (1-bromo-1,3,4-trideoxy-1,4-C-[(R, S)-phenylphosphinylidene]-glycero-tetrofuranose) by the action of bromine in aqueous medium. The bromo substituent of the phospholane was substituted by treatment with amines or an azide anion to afford novel glycoside derivatives of phosphanyl sugar analogs such as 2-amino-3-hydroxy-1-phenylphospholane (3,4-dideoxy-1,4-C-[(R, S)-phenylphosphinylidene]-glycero-tetrofuranosylamine) and 2-azido-3-hydroxy-3-methyl-1-phenylphospholane 1-oxides with retention of the configuration. The 1,3-dipolar cycloaddition of the 2-azido derivative of the phospholane with alkynes gave 3-hydroxy-3-methyl-1-phenyl-2-(triazol-1′-yl)phospholane 1-oxides as a novel triazole-derived nucleoside of phosphanyl sugar analogs.

A main group-catalyzed method for the synthesis of aryl- and heteroarylamines by intermol. C-N coupling is reported. The method employs a small-ring organophosphorus-based catalyst (1,2,2,3,4,4-hexamethylphosphetane) and a terminal hydrosilane reductant (phenylsilane) to drive reductive intermol. coupling of nitro(hetero)arenes with boronic acids. Applications to the construction of both Csp2-N (from arylboronic acids) and Csp3-N bonds (from alkylboronic acids) are demonstrated; the reaction is stereospecific with respect to Csp3-N bond formation. The method constitutes a new route from readily available building blocks to valuable nitrogen-containing products with complementarity in both scope and chemoselectivity to existing catalytic C-N coupling methods.
