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