Bis(trimethylsilyl)ethyne and hexyldimethylsilane undergo transsilylation reactions in the presence of Wilkinson's catalyst to give 1-hexyldimethylsilyl-2-trimethylsilylethyne and bis(hexyldimethylsilyl)ethyne.The reaction is faster in air than in argon but oxidation of the silane takes place which significantly reduces the yield.

Organofluorophosphonium salts of the formula [(C6F 5)3-xPhxPF][B(C6F5) 4] (x = 0, 1) exhibit Lewis acidity derived from a low-lying σ* orbital at P opposite F. This acidity is evidenced by the reactions of these salts with olefins, which catalyze the rapid isomerization of 1-hexene to 2-hexene, the cationic polymerization of isobutylene, and the Friedel-Crafts-type dimerization of 1,1-diphenylethylene. In the presence of hydrosilanes, olefins and alkynes undergo efficient hydrosilylation catalysis to the alkylsilanes. Experimental and computational considerations of the mechanism are consistent with the sequential activation and 1,2-addition of hydrosilane across the unsaturated C-C bonds.
