Abstract

Abstract The preparation of the first silacyclopropanes, all derivatives of 7, 7-dimethyl-7- siladispiro [2.0. 2.1] heptane, by magnesium-induced ring closure reactions of 1, 3-dihalides, is described. Mass spectral and 1 H, 13 C and 29 Si NMR spectral data, as well as the unusually high chemical reactivity of these compounds support the assigned silacyclopropane structures.
