Applications of Phase Transfer Catalysis, VIII. Synthesis and Some Reactions of Tetrasubstituted 6,6-Dihalogenobicyclohex-3-en-2-ones

The reaction of tetrasubstituted cyclopentadienones 1 with dichlorocarbene or dibromocarbene gives specifically the 6,6-dihalogenobicyclohex-3-en-2-ones 2 and 3.Reductive ring opening of 2 or 3 with LiAlH4 cleanly yields the tetrasubstituted 3-halogenophenols 4 and 5.Reaction of 2 or 3 with methylmagnesium iodide leads to 2,4-cyclohexadien-1-ones 13 and to 1-halogeno-5-methylene-1,3-cyclohexadienes 14.
