General description

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

Application

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