Application

3-(Trimethylsilyl)-2-propynal can be used as a reactant to synthesize:
  • Silicon-containing polyfunctional chiral tertiary phosphine oxides, which are employed as building blocks to prepare polydentate amphiphilic ligands for the design of novel metal complex catalysts.
  • 4-trimethylsilyl-1H-1,2,3-triazole-5-carbaldehyde by reacting with trimethylsilyl azide.
  • 4-trimethylsilylethynyl-4H-pyran-3,5-dicarbaldehyde via trimerization reaction in the presence of DABCO (1,4-diazabicyclo-[2.2.2]octane) as a catalyst.
