ron hexafluorophosphate (2i) react with sodiomalononitrile highly regioselectively to give functionalised gem-disubstituted cyclohexadiene complexes which are potential precursors of 4,4-disubstituted cyclohexenones. The reactions of these and related complexes with other carbanions are also reported.
