Application
(Triphenylsilyl)acetylene may be used in the synthesis of:
- selenothioic acid S-alkyl esters
- methyl 2-(di{ 3, 5-bis[(triphenylsilyl)ethynyl]phenyl}-phosphino)benzoate
- 2-(di{3,5-bis[(triphenylsilyl)ethynyl]phenyl}-phosphino)benzoic acid
General description
(Triphenylsilyl)acetylene is a terminal alkyne. Rhodium-catalyzed asymmetric addition of (triphenylsilyl)acetylene to diphenylphosphinylallene is reported.

The presence of an acid was found to be essential in the rhodium-catalyzed asymmetric addition of terminal alkynes to diarylphosphinylallenes giving exo-enynes in high yields with high regio- and enantioselectivity. The stereochemical outcome is determined at the protonolysis of the
