ABSTRACT:
The present invention relates to a process for the preparation of higher alkyl acrylic acid esters which comprises contacting and reacting under ene reaction conditions one or more olefins with one or more alkyl acrylic acid esters in the presense of a catalytically effective amount of an alkoxy aluminum dichloride having a formula R--O--AlCl.sub.2, wherein R is alkyl, aryl or a group having a formula R'--C(O)--, wherein R' is alkyl or aryl.
