1,4-Dichlorobut-2-ene is a chlorinated butene. It is an intermediate in the industrial production of chloroprene, and the main impurity in technical grade chloroprene.^[2] The (E)-isomer is also one of the starting materials for Birman's total synthesis of the poriferic natural product sceptrin.^[3]

Production of chloroprene

Chloroprene is a monomer for the production of

polymerization inhibitors gives crude chloroprene.^[4]
