General description

3-Chloro-2-methyl-1-propene is the reactant for the synthesis of cyclobutanone.

Application

3-Chloro-2-methyl-1-propene was used to study ring opening polymerization of oxirane derivatives using organotin phosphate condensate. It was used to study cationic polymerization of 3-Chloro-2-methyl-1-propene using using AICI3 and A3IBr, as initiators.
