Abstract

The meso form of (RMeSiOH)₂ [R = Si(SiMe₃) ₃] (2) was synthesized exclusively by hydrolysis of a diastereomeric mixture of (RMeSiCl)₂ (1). The novel cyclic metal disiloxides (E)-(RMeSiO)₂Ti(OEt)₂ (3) and [(Z)-(RMeSiO) ₂]₂Zr • HNEt₂(4) are readily prepared from the reaction of meso-2 with Ti(OEt)₄ and Zr(NEt₂) ₄, respectively. The results of X-ray structure analyses reveal complexes 3 and 4 to be strained five-membered ring compounds forming a dimeric structure and an adduct with diethylamine.
