A process for the production of polyalkyl tetrahydronaphthalenes is disclosed wherein a cyclialkylation reaction between an olefinic compound of the general Formula <IMAGE> wherein R5, R6 and R7 are independently defined and each is a substituent which does not interfere with a Friedel-Crafts type alkylation reaction, and a substituted benzene compound is carried out in the presence of an alkyl halide, a Lewis acid and a phase transfer agent. The subject process, which may be practiced in an unhalogenated hydrocarbon solvent, produces the desired compounds in a surprisingly high yield, with a surprisingly high selectivity to the desired product, and at a relatively high rate of reaction, using safer solvents and better, more convenient, or less expensive process methodology than many processes known heretofore.
