PURPOSE: To regioselectively and efficiently obtain the compound, concerned in electron transport, etc., in living bodies, having diverse physiological activities and useful as medicines, etc., without requiring the protection of carbonyl group by reacting an allyltrifluorosilane with a quinone. CONSTITUTION: This method for producing an allylquinone of formula III (R to R are each H, an alkyl, an aryl, an alkenyl, an alkoxy, cyano or a halogen; R and R , R and R , R and R or R and R , together with C to which they are respectively bound, may form a ring; R to R are each H, an alkyl, an aryl, an alkenyl, an alkynyl, an alkoxy, OH or R and R , together with C to which they are respectively bound, may form a ring) [e.g. 2-(3-methyl-2- butenyl)-1,4-benzoquinone] is to react an allyltrifluorosilane of formula I [e.g. (E)-2-butenyltrifluorosilane] with a p-quinone of formula II (X is H or a halogen) (e.g. 1,4-benzoquinone), preferably in the coexistence of an oxidizing agent.
