Pericyclynosilanes: Synthesis of a New Class of Cyclic Organosilicon Compounds

The pericyclynosilanes, systematically known as cyclopoly(silapropynylenes), (R2SiCC)n (where R=Me or Ph, n>/=5) have been synthesised, in high yield, by the reaction of the dilithium derivatives of diorganodiethynylsilanes with the corresponding diorganodichlorosilanes, and the dodecamethyl (n=6) and dodecaphenyl (n=6) derivatives have been isolated and fully 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.
