A process is described for purification of a reaction product mixture of cyclobuteno-4-haloarene containing aliphatic halide impurities. The product mixture is contacted with a tertiary amine under conditions effective for conversion of aliphatic halides to soluble species which can be removed from the mixture by extraction. The process can be used, for example, in the recovery of 4-bromobenzocyclobutene from a reaction product mixture containing aliphatic halide by-products such as 1-bromo-2-(2-bromoethyl)benzene.
