Highly efficient cyclization of o-iodobenzoates with aldehydes catalyzed by cobalt bidentate phosphine complexes: A novel entry to chiral phthalides

Methyl 2-iodobenzoates 1a-c undergo cyclization reactions with various aromatic aldehydes 2 a-m (RC6H4CHO: R=H 2a, 4-CH3 2b, 4-tBu 2 c, 4-OMe 2 d, 3-OMe 2 e, 4-Cl 2 f, 4-CF3 2g, 4-CN 2h, 4-Ph 2i; benzo[d][1,3]dioxole-5-carbaldehyde (2j), -napthaldehyde (2k), benzofuran-2-carbaldehyde (21), and isonicotinaldehyde (2m)) in the presence of [CoI2(dppe)] (dppe = 1,2-bis(diphenylphosphino)ethane) and Zn powder in dry THF at 75 degrees C for 24 h to give the corresponding phthalide derivatives 3a-m and 3q-t in good to excellent yields. Under similar reaction conditions, less reactive aliphatic aldehydes, heptanal (2n), butyraldehyde (2o), and 2-phenylacetaldehyde (2p) also underwent cyclization reactions with la to provide 3n-p, respectively, in fair to good yields. The catalytic reaction can be further extended to cinnamyl aldehyde (2q) with la to give the corresponding phthalide derivative 3u. This synthetic method is compatible with a variety of functional groups on the aryl ring of 2. The high efficiency of the cobalt catalyst containing a dppe (dppe=1,2-bis(diphenylphosphino)ethane) ligand encouraged us to investigate the asymmetric version of the present catalytic reaction by employing bidentate chiral ligands. Thus, aromatic aldehydes 2a-c, 2f, and 2g undergo cyclization with 2-iodobenzoate (1a) smoothly in the presence of [CoI2(S,S)-dipamp}] ((SS)-dipamp(1S,2S)-(+)-bis[2-methoxyphenyl]phenylphosphino)ethane) and zinc powder in THF at 75 degrees C for 24 h, giving the corresponding (S)-phthalides 4a-e in 81-89% yields with 70-98% ee. A possible mechanism for the present catalytic reaction is proposed.

High transport parameters and free volume of perfluorodioxole copolymers

Permeability (P) and diffusion (D) coefficients of perfluoro-2,2-dimethyl-1,3-dioxole-tetrafluoroethylene copolymers were determined with respect to different gases (He, H-2, O-2, N-2, CO2, hydrocarbons C-1-C-3). The copolymers with large content of perfluorodioxole comonomer exhibit high permeability with respect to lighter gases comparable to that of poly(trimethylsilyl propyne). However, the copolymers studied are much more permselective than the latter polymer. Free volume as estimated via Bondi’s method and free volume size distribution parameters which were determined by means of positron annihilation lifetimes (PAL) method are also unusually high if compared with other glassy polymers. A novel correlation of the P and D values, as well as of the solubility coefficients S with the PAL parameter tau(4)I(4) are reported.

Intermolecular interactions in target organophilic pervaporation through the films of amorphous Teflon AF2400

Organic-organic pervaporation was studied for high free volume material-amorphous Teflon AF2400 (copolymer of 2,2-bis-trifluoromethyle-4,5-difluoro dioxole and tetrafluoroethylene). Individual organic components-acetone (A), chloroform (Ch) and methanol (M) that are capable of forming azeotrope mixtures as well as binary mixtures A-Ch and M-Ch were tested as penetrants. The process was studied at different temperatures (10-50 degrees C) over a wide range of composition of mixtures (10-90%). Evidence of formation of associates between the components in the mixtures in the liquid phase and during mass transfer through the films were obtained. IR spectra and quantum-chemical calculations supported these conclusions. (c) 2005 Elsevier B.V. All rights reserved.

Polymers based on a novel 1,3-perfluorodioxole for use as a soft polymer pellicle in 157nm lithography

A series of copolymers of tetrafluoroethylene and 4-trifluormethoxy-1,3-perfluorodioxole (TFETFMD) were prepared as well as a homopolymer of the dioxole (TEMD) using various free-radical initiators. The copolymers were characterized by F-19 NMR, TGA, DSC and VUV measurements. The transparency at 157nm increased with increasing dioxole content reaching an alpha (mum(-1)) = 0.76 for an unoptimized homopolymer of the dioxole prepared with a perfluorinated peroxide initiator. Exposure studies of the dioxole homopolymer at 157 nm indicate rapid formation of carbonyl species and therefore an anticipated short lifetime as a potential polymer pellicle for 157 nm lithography.
