Description

General description

Crotyl chloride reacts with trichlorosilane in the presence of tertiary amine and copper salts to give the corresponding allyltrichlorosilanes.

Application

Crotyl chloride has been used:

• to investihgate the kinetics of the reactions of atomic chlorine with series of unsaturated aldehydes and ketones at 298K, to probe structure-reactivity relationships
• in the preparation of (E)-crotyltrichlorosilane
