Chlorotrimethylsilane (TMSCl): an efficient silicon-based Lewis acid mediator in allylic alkylation using a diethylzinc reagent†
Abstract
Chlorotrimethylsilane (TMSCl) was a highly efficient catalyst in the allylic alkylation of 1,3-diaryl-2-propenyl acetates with a diethylzinc reagent, in which various 1,3-diaryl-2-propenyl acetates are efficiently transferred to 1,3-diarylpent-1-enes in good to excellent yields.
