Abstract

PURPOSE: A trihaloethane is heated in the presence of a diazabicycloalkene hydrohalide to produce the titled substance used as a monomer for high polymer synthesis or a synthetic intermediate in high selectivity.
CONSTITUTION: A trihaloethane such as 1,1,2-trichloroethane is heated at 230W 320°C in the presence of a diazabicycloalkene hydrochloride or hydrobromide of the formula (n is 3W11, preferably 3,5, or 11) to produce a vinylidene halide such as vinylidene chloride. The reaction may be conducted either in liquid or gas phase, however, when it is conducted in gas phase, the diazabicycloalkene hydrohalide is preferably supported on a carrier such as silica gel. When it is conducted in liquid phase, a solvent may be used and a small amount of autioxidant may be added to the reaction system.
