PROCESS FOR THE PRODUCTION OF 1-ACETOXY-3-(SUBSTITUTED PHENYL)PROPENES

摘要

Compounds represented by the general formula (I) can be produced by reacting a benzene compound represented by the general formula (IV) or (V) with an alkenylidene diacetate represented by the general formula (VI) in the presence of a catalyst comprising (a) a boron halide, (b) a triflate of a group 11 element, (c) a halide of a group 12 element, and (d) at least one member selected from among triflates and halides of tin and elements of atomic numbers of 58 and 66 to 71: (I) (IV) (V) (VI) wherein R<1> and R<2> are each H or C1-10 alkyl; A is a substituted phenyl group corresponding to a compound of the general formula (IV) or (V); R<3> and R<4> are each C1-4 alkyl; m is 0 or 1 to 4; n is 1 to 5; and k is 1 or 2.
