Coenzyme Q10 was synthesized by the isocoupling reaction between Grignard reagent of 2-methyl-3-chloro-4-(2'-methyl-3',4',5',6'-tetramethoxyphenyl)butene and solanesyl bromide followed by oxidation of the corresponding toluene derivative. It is therefore successfully indicated that allylic Grignard reagent can be isocoupled with allyl halide via a six-membered ring as transition state.

Key words: Grignard reagent, isocoupling, solanesol, coenzyme Q10
