compound, prepared readily by the cross-coupling reaction of β-bromoallyltrimethylsilane and the Grignard reagent from β-bromoallyldimethylamine, is an effective reagent as 2,2′-biallyl diradical synthon to give [6.6] and [6.7] ringsystems by tandem cycloaddition reactions. 1,2-Dimethylenecyclohexanes can also be isolated in good yield.
