Methyl Vinyl Carbonate

Carbonic acid cyclic vinylene ester.

Methyl vinyl carbonate.

Indolines and indoles undergo selective c h allylation with vec in the presence of rhodium iii. 4 vinyl 1 3 dioxolan 2 on e vec is a cyclic carbonate that can be synthesized from acrolein by reacting with sulfur ylide and co 2. 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. 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.

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.

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