Chloroprene (2-chloro-1,3-butadiene) is one of the few conjugate dienes that are mass-produced and utilized on an industrial scale. Although it is an economically very attractive resource, most of its use is for polymerization, producing chloroprene rubber. Its application to organic synthesis as a source of a C 4 -unit is limited to Diels−Alder reactions 1 and reactions of its Grignard reagent. 2 Utilization of chloroprene for synthesis of fine chemicals, accordingly, is an ...
