Methyl Vinyl Carbonate

Ove was also prepared by reaction with β butyrolactone or sodium hydrogencarbonate in the presence of tbab as the catalyst.

Methyl vinyl carbonate.

2 oxo 1 3 dioxolan 4 yl methyl vinyl ether ove was synthesized with high yield by addition reaction of glycidyl vinyl ether with carbon dioxide using tetrabutylammonium bromide tbab as a catalyst. Indolines and indoles undergo selective c h allylation with vec in the presence of rhodium iii. Carbonate solvents are generally considered to be inadequate electrolytes for li s batteries but the latest investigations of pan s 67 69 or ac s 70 composite electrodes have shown extremely high reversible capacities in mixtures. The ruthenium catalyzed transfer hydrogenation th of vec in the presence of 2 propanol forms 1 2 butanediol.

Vinyl ethylene carbonate cas 4427 96 7 synthesis structure density melting point boiling point. Carbonic acid cyclic vinylene ester. The proposed mechanism suggests that it starts from the combination of vinyl pinacolboronates and carbonate to form the intermediate ii which is calculated to be exothermic by 7 4 kcal mol. The vinyl carbonate 13 152 gives only copolymerization the ketene acetal 11 153 and the methyl vinyl ether 14 152 give both copolymerization and chain transfer in styrene polymerization whereas with the benzyl vinyl ethers 12 153 15 8 and 16 18 151 chain transfer is the only reaction detected.
