A TiCl4/Et3N combination proved to be effective for the selective oxidation of propargylic alcohols into α,β-acetylenic aldehydes in good yields. Treatment of 2-hexyne-1,6-diol with TiCl4/Et3N provided 6-hydroxy-2-hexynal in good yield.
TiCl4/Et3N组合被证实对将炔丙醇选择性氧化为α,β-炔醛有效,且产率良好。采用TiCl4/Et3N处理2-己炔-1,6-二醇,可得到高产率的6-羟基-2-己炔醛。
