Descripción

General description

3-Trimethylsiloxy-1-propyne is an organosilicon compound. It is reported as silylated acetylenic monomer and its polymerizability has been studied in the presence of combined catalyst iron(III) propanoate-triethylaluminium. N₂ laser light-induced aerosol particle formation from 3-trimethylsiloxy-1-propyne (trimethyl(2-propynyloxy)silane) and acrolein has been reported. The infrared laser-photosensitized (SF₆) decomposition of trimethyl(2-propynyloxy)silane is reported to afford a multitude of unsaturated hydrocarbons and a solid polydimethylsiloxane phase.

Application

3-Trimethylsiloxy-1-propyne (Trimethyl(2-propynyloxy)silane) may be used in the synthesis of polytrialkylsiloxy-substituted macromolecules. It may be utilized in the preparation of functionalized 4-enynes and 1,4-dienes.
