Abstract

1,207,272. m-Chlorophenyl acetylene. LABOFINA S.A. 1 Nov., 1968, No. 51860/68. Heading C2C. [Also in Division C5] In Example IV, m-chlorophenyl acetylene is obtained by dehydrobrominating m-chloroalpha,beta-dibromoethyl benzene by heating in the presence of diethylene glycol containing an excess of KOH.
