Monoorganosilicon(IV) Complexes of 2-Aminocyclopentene-1-carbodithioic Acid and its N-/S-Alkyl Derivatives: Synthesis and Characterization

Abstract

2-Aminocyclopentene-1-carbodithioic acid (ACDA) and its N-/S-alkyl derivatives of methylsilicon(IV) chloride have been synthesized by the reactions of MeSiCl3 with sodium salt of ACDA and its N-/S-alkyl derivatives in 1:1 and 1:2 molar ratios. All these complexes have been characterized by elemental analysis, molecular weight measurements and spectroscopic (IR, 1H and 13C NMR) studies. The central silicon atom is coordinated to two sulphur atoms or one sulphur atom and one nitrogen atom of the ligand moiety in all of these derivatives, resulting in five and six coordination.
