PROCESS FOR PREPARATION OF GERANYL ARYL SULFONES

摘要

A process for the preparation of geranyl aryl sulfones represented by the general formula (4): (4) [wherein Ar is optionally substituted aryl; and the wavy line represents either of E/Z geometrical isomers or a mixture of both], characterized by reacting an allyl halide represented by the general formula (3): (3) [wherein X is halogeno; and the wavy line is as defined above] with an arylsulfinic acid salt in the presence of a phase−transfer catalyst and an inorganic salt.
