Synthesis of Some Ketimine Derivatives of Silicon(IV)

Abstract

Synthese einiger Ketiminderivate des vierwertigen Siliciums A brief survey of the literature revealed that so far very few silicon Schiff base complexes have been reported [1, 2]. Although, the reactions of metal alkoxides of a number of metals of III, IV, V and VI groups of the periodic table with Schiff bases have been found to be facile and straight forward, the reactions of alkoxy silanes with azomethines as well as other nitrogen donor ligands have been reported to be quite slow [3]. However, silicon tetraacetate has been found to be a suitable starting material for such reactions and this has been used in the present studies as well. In previous communications from these laboratories, the reactions with bifunctional tridentate or tetradentate Schiff bases have been reported [4, 5]. The present paper describes the synthesis and properties of silicon complexes with monofunctional bidentate Schiff bases of the type 1 .
