ABSTRACT:
Halogenated acetylenic compounds are prepared by irradiating a mixture of a reactant and a sensitizer with coherent light. The reactant has the general formula R--C.sub.2 HX.sub.4, R--C.sub.2 H.sub.2 X.sub.3, or R--C.sub.2 HX.sub.2 where X is Cl, Br, or I, and R is H or another non-interfering group. The sensitizer has a higher thermal activation energy for its lowest energy dissociation reaction than does any part of said reactant.
