characterised; when the organic substituents present in the diorganodiethynylsilane differ from those of the diorganodichlorosilane, a redistribution reaction is observed, leading to a product in which the organosilicon units are randomly distributed.

The hydrogenation of bistrimethylsilylactylene, bis(trimethylsilyl)-1,3-diynes, and related silylalkynes giving the corresponding saturated compounds were achieved by using diimide prepared in situ from p-toluenesulfonyl hydrazide in diglyme. The present method was applicable to the synthesis of saturated 12- and 18-membered oligosilacycloalkanes.

The silapericyclyne, (Ph2SiC≡C)6 was found to undergo spontaneous conformational resolution into the chair and boat conformations by crystallization from THF-MeOH. In solution, these two isomers rapidly interconvert, and could not be separately detected even at low temperature by 1H NMR.
