Abstract

Desulfurization of thioacetals with the low valent titanium species Cp2Ti [P (OEt) 3] 2 in the presence of trialkylsilanes afforded the corresponding tetraalkylsilanes. Allylsilanes were obtained regioselectively using β, γ-unsaturated thioacetals or 1, 3-bis (phenylthio) alk-1- enes as starting materials. The similar titanocene (II)-promoted reactions of these organosulfur compounds with triethylgermane and tributylstannane gave ...
