1-Substituted prop-2-ynyl mesylates cause propargylation of aldehydes with tin(II) iodide, tetrabutylammonium iodide and sodium iodide in 1,3-dimethylimidazolidin-2-one to produce 2-substituted but-3-yn-1-ols, while 3-substituted prop-2-ynyl mesylates cause allenylation of aldehydes under the same conditions as those of the propargylation by 1-substituted prop-2-ynyl mesylates to produce 2-substituted
1-取代的丙-2-炔基甲磺酸盐在 1,3-二甲基咪唑啉-2-酮中引起醛与碘化锡 (II)、碘化四丁基铵和碘化钠的炔丙基化,生成 2-取代的丁-3-yn-1-醇,而3-取代的prop-2-ynyl甲磺酸酯在与1-取代的prop-2-ynyl甲磺酸酯的炔丙基化相同的条件下引起醛的烯丙基化以产生2-取代的buta-2,3-dien-1-ols。
