Abstract Hexamethylcyclotrisilthian and dibromodimethyl-silane upon heating form liquids which, by proton nuclear magnetic resonance spectroscopy, are shown to be mixtures of molecules. The equilibria resulting from exchange on the dimethylsilicon moiety of bridging sulfur atoms with bromine atoms are shifted strongly towards ring compounds. At equilibrium, measured at 150° and 200 °C, in addition to relatively small amounts of short chain molecules, two sizes of ring molecules are seen, with… CONTINUE READING
