Phenylacetylene is a prototypical terminal acetylene, undergoing many reactions expected of that functional group. It undergoes semihydrogenation over Lindlar catalyst to give styrene. In the presence of base and copper(II) salts, it undergoes oxidative coupling to give diphenylbutadiyne. In the presence of metal catalysts, it undergoes oligomerization, trimerization, and even polymerization. ric flair kinderWebView 64984-31-2/2-Phenylethyne-1-sulfonamideinformation and document regarding 2-Phenylethyne-1-sulfonamide, including NMR, HPLC, LC-MS, UPLC & more. ric flair last match bunkhouse battle royalWebLe phényléthyne ou phénylacétylène est un hydrocarbure alcynique contenant un groupe phényle.
