3-dimethyl-3-silahepta-1,4-diene as the major product from addition of dimethylsilanediyl (dimethylsilylene) to cis,cis-hexa-2,4-diene is believed to result from a concerted 1,5-sigmatropic hydrogen shift in the rearrangement of the vinylsilacyclopropane intermediate formed by concerted 1,2-cis-addition of the silanediyl.
