General description
Laser-induced polymerization of gaseous ethynyltrimethylsilane was used for efficient chemical vapour deposition of polycarbosilane films. Ethynyltrimethylsilane acts as substrate for nickel-catalyzed cross-coupling with benzonitriles.
Application
Ethynyltrimethylsilane was used in:
- microwave-assisted, one-pot, three-step Sonogashira cross-coupling-desilylation-cycloaddition reaction for the preparation of 1,4-disubstituted 1,2,3-triazoles
- synthesis of poly(ethynyltrimethylsilane) containing Pd (II) coordination sites
- pyrazole synthesis via 1,3-dipolar cycloaddition of diazo compounds to acetylenes
