Allylacetic acid Chemical Properties,Usage,Production

Description

Allylacetic acid (allyl acetate) is a derivative of acetate. It is the acetate ester of allyl alcohol. It is useful industrial intermediate. It is the precursor of some special polymer such as drying oils. It can also be used as a useful allylating reagent for catalyzing the allylation of aldehydes, and also allylation of aryl bromides in the palladium-catalyzed cross-coupling reaction. It has also demonstrated that it is a potential fumigant against grain beetle pests; study has shown that doses of 50–150 mg litre?1 with 24–120-h exposures are necessary to achieve 100% mortality of all life stages against grain beetle pests. Study has also shown that ally acetate is an effective oxidants during the Palladium— Iminophosphine-Catalyzed Homocoupling of Alkynylstannanes and Other Organostannanes
