A reagent system of 1-alkyne, SnCl4, and Bu3N alkynylates aldehydes, acetals, and enones under mild reaction conditions giving acetylenic alcohols, acetylenic ethers, and acetylenic ketones, respectively, in high yields. Alkynyltrichlorotins are shown to be the reactive species for these reactions.
一种试剂体系,由1-炔烃、四氯化锡和三丁基膦组成,在温和反应条件下能分别高效地将醛、缩醛和烯酮转化为炔丙醇、炔基醚和炔基酮。实验结果表明,在这些反应中,炔基三氯化锡是活性物种。
