Abstract

NEW MATERIAL:An enol carbonate of acetoacetic ester expressed by the formula (R is 1W4C alkyl).
EXAMPLE: An enol carbonate of methyl acetoacetate.
USE: A synthetic raw material for organic compounds, having a high reactivity similar to that of phosgene, easily handleable due to no toxicity, and useful as a raw material for diphenyl carbonate or polycarbonate.
PROCESS: An acetoacetic ester, e.g. methyl acetoacetate or ethyl acetoacetate, is reacted with phosgene or trichloromethyl chloroformate to give the compound of the formula. The reaction is carried out in a solvent, e.g. methylene chloride, under cooling.
