Abstract

α, ω-Bis (vinyldimethylsilyl) alkanes (1-4) of the general formula CH2 CH (CH3) 2Si (CH2) n (CH3) 2SiCH CH2 (where n= 1-4) undergo effective silylative coupling (SC) polycondensation, if catalyzed by [RuCl2 (PPh3) 3](II) or [RuHCl (CO)(PPh3) 3](III), giving linear polymers (5-8)(M w= 7300-8500) containing a mixture of trans-1, 2-and gem- fragments, but in the presence of [{RuCl2 (CO) 3} 2](I) as a catalyst, highly stereoselective ...
