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
