Silane Cross-Coupling Agent

The cross-coupling reaction is a highly useful methodology for the formation of carbon-carbon bonds. It involves two reagents, with one typically being a suitable organometallic reagent - the nucleophile - and the other a suitable organic substrate, normally an unsaturated halide, tosylate or similar - the electrophile.

Trimethylsilylacetonitrile; TMSAN; Cyanomethyltrimethylsilane
  • Following lithiation with LDA may be alkylated with organobromides
  • Cyanomethylates quinolinium methiodides
