Abstract:
     The present invention refers to a method for synthesis of 1-trisilyl-propine. It uses acetylene as raw material, which carries out Grignard reaction for its selected active hydrogen atom, and forms 1-trisilyl-ethyne through silanization. The 1-trisilyl-ethyne is used to obtain 1-trisilyl-propine through another Grignard reaction and methylation. The said product contains hexamethylsilicone less than 350 ppm, with purity above 99.5% meeting purity requirement of high molecular poly-1-trisilyl-propine produced by cation double decomposition and catalytic polymerization.
