Water → 2,2,2-Trichloroethyl 2,4-bis(trichloromethyl)benzo[1,3]dioxin-6-carboxylate

Participants

Reaction Steps

A mixture of 2,4-bis(trichloromethyl)benzo[1,3]dioxin-6-carbonyl chloride (5.0 g.) and 2,2,2-trichloroethanol (25 ml.) was warmed on a steam bath for 2 hours. The reaction mixture was cooled, and water was added to produce a white precipitate which was filtered off and crystallised from a mixture of ether and petroleum ether (b.p. 60°-80° C.) to give 2,2,2-trichloroethyl 2,4-bis(trichloromethyl)benzo[1,3]dioxin-6-carboxylate, m.p. 129°-130° C.
