Abstract
A process for producing an allyl-substituted phenol compound is described, which comprises a combination of a first step in which a phenol is reacted with an allyl halide in the presence of an alkaline aqueous medium to allyl-etherify the phenol and a second step in which the reaction product obtained in the first step and containing the allyl-etherified phenol is subjected to a Claisen rearangement reaction in the absence of a medium. Also, a compound obtained by the above process is described.
