Notes:
Acyclic diene polycondensation (ADP) of diallyldiorganosilanes (CH2=CHCH2)2SiR2 (where R = Me, Ph), in the presence of various ruthenium and rhodium complexes, led predominantly to linear silylene-propenylene oligomers. Ruthenium catalysts (e.g. RuCl2(PPh3)3, RuHCl(CO)(PPh3)3, and RuCl(SiMe3)(CO)(PPh3)2) were found to be more efficient than the rhodium ones. The reaction proceeds via preliminary catalytic isomerization of allylsilane to silyl-1-propenes followed by their oligococondensation. © 1997 John Wiley & Sons, Inc.
