Abstract
Abstract Details are provided for the preparation of three 1-oxa-2-silacyclohexanes; namely, 1-oxa-2,2-diphenyl-2silacyclohexane, 1-oxa-2,2-dimethyl-2-silacyclohexane and 1-oxa-2-methyl-2-silacyclohexane from magnesium halide-catalyzed reactions of some dichlorosilanes and magnesium metal in tetrahydrofuran. A thorough discussion of their mechanism of formation is also presented and syntheses of the following compounds are reported for the first time: 1-oxa-2-methyl-2-silacyclohexane (the first reported compound of this type containing a chiral silicon), (4-bromobutoxy)chlorodimethylsilane and (4-bromobutoxy)-chloromethylsilane.
