Boron trifluoride promoted transdithioacetalization of alpha-chloroacetals with 1,2-benzodithiol affords good yields of 2-(1-chloroalkyl)1-3-benzodithioles, which dehydrochlorinates very satisfactorily to the corresponding 2-alkylidene-1,3-benzodithioles.

Abstract
Boron trifluoride promoted transdithioacetalization of alpha-chloroacetals with 1,2-benzodithiol affords good yields of 2-(1-chloroalkyl)1-3-benzodithioles, which dehydrochlorinates very satisfactorily to the corresponding 2-alkylidene-1,3-benzodithioles.
