method for the preparation of allyl chlorides from Baylis–Hillmanadducts has been developed using triphosgene/pyridine system. This method is best illustrated by its advantages like operational simplicity, excellent yields, short reaction time, simple procedure and stereoselectivity. The preparation of allyl chlorides from Baylis-Hillmanadducts has been described using triphosgene & pyridine system

has been developed by the C–H functionalization of anilides with Morita–Baylis–Hillman (MBH) bromides in the presence of copper chloride, TBHP and acetic acid. Unsubstituted as well as ortho/meta-substituted anilides exclusively give rise to the para-allylated products, whereas para-substitution brings about the formation of ortho-allylated anilides.
