Abstract

The thermal decarboxylation of alkali trichloroacetates in aprotic solvents in the presence of olefins has been investigated. The isolation of dichlorocyclopropanes in good yields demonstrates the formation of CCl~2~ as an intermediate. By this method, the reaction of base‐sensitive acceptors such as allylchloride with CCl~2~ may be successfully accomplished, since it proceeds under essentially neutral conditions. Vinyl acetate gave, in addition to the cyclopropane derivative, 1‐trichloromethylethyl acetate.

## Abstract Sodium trichloroacrylate decomposes in 1,2‐dimethoxyethane at 90° to give quantitative yields of CO~2~ and NaCl. Evidence is presented that this decarboxylation involves the trichlorovinyl anion, CCl~2~CCl^−^, as an intermediate.
