Organosilicon Compounds and Organosilicon Polymer Intermediates
Abstract
Studies of the highly reactive Si-C bonds of hexamethylsilacyclopropane and 1,1-dimethy1-3,4-bis(trimethylsilyl)- silacyclopropene and of the reactive Si-Si bond of octamethyl1-1,2- disilacyclobutane completed. RP- and RAs-bridged ferrocenophanes were prepared and their reactions with organolithium reagents studied. Ferrocenylenephenylphosphine polymers were prepared for use as ligands in catalysis studies. Their cobalt complexes are active hydroformylation catalysts. A novel and useful route to acylsilanes based on the carbon monoxide-derived acyllithium reagents has been developed. The hydrolysis of dichlorosilane, was found to give cyclic oligomers, with n equals 4 through 23, in decreasing amounts. Linear species also were prepared and studied. A study of the transition metal chemistry of cyclodiisopropylsilane was initiated with the ultimate objective of preparing transition metal silicides. A study of the reactivity of calcium disilicide derived 'reactive silicon' and 'silicon mono halides' was started.
