Reactions of Unsaturated Compounds with Silicon Difluoride. Part I. Acetylene

Abstract
The reaction of acetylene with silicon difluoride at low temperatures has been studied. Three products have been identified as volatile species after the reaction: tetrafluorodisilacyclobutene, 3,4-tetrafluorodisilahex-1-yne-5-ene, and 5,6,7-hexafluorotrisilanorborn-2-ene. Spectroscopic data for the compounds are presented, together with a possible mechanism to account for the formation of the observed products.
