Toluene → 1-Propyl-1,1,3,3-tetramethyldisiloxane

Participants

Reaction Conditions

Reaction Steps

An 80 mL Fischer-Porter high pressure bottle was charged with tetramethyldisiloxane (10.0 g), toluene (10.0 g) and Wilkinson's catalyst ((PPh3)3RhCl, 40 ppm), stirred and brought to 50° C. The bottle was attached to a manifold and pressurized with propylene (40 psig) and maintained at 50° C. for 2 h. The pressure was vented, and the reaction was sampled for GC analysis; found M′MR product and MRMR byproduct (40:60). The resulting mixture of materials was used without further purification, yield 14.1 g.
