General description

Crotyl chloride reacts with trichlorosilane in the presence of tertiary amine and copper salt to give the corresponding allyltrichlorosilane[1].

Application

Crotyl chloride was used in kinetics measurements of reactions of atomic chlorine with series of unsaturated aldehydes and ketones at 298K[2]. (E)Crotyl chloride was also used in the preparation of (E)-crotyltrichlorosilane[3].
