THE SYNTHESIS AND SOME PROPERTIES OF 1-THIA-3-SILACYCLOBUTANES AND 1-THIA-3-SILACYCLOPENTANE

3,3-Dimethyl-1-thia-3-silacyclobutane has been obtained by the reaction of Me2Si(CH2Cl)2 with potassium hydrosulfide in abs. ethanol.Intramolecular hydrosilylation of isomeric vinylthioethyldiethylsilanes, HEt2Si-X-SCH=CH2 (X = CH(CH3) or CH2CH2) proceeds selectivity as α-addition to afford cyclic compounds, and , respectively.This ring closure reaction is catalyzed by (Ph3P)3RhCl.The endocyclic Si-C bond of 3,3-dimethyl-1-thia-3-silacyclobutane undergoes cleavage upon treatment with ethanolic KOH leading to Me2(EtO)SiCH2SCH3 and O(SiMe2CH2-SCH3)2.The reaction of 3,3-dimethyl-1-thia-3-silacyclobutane with ethanolic HgCl2 involves ring opening and formation of a complex, O2.
