simple, and straightforward one-pot reaction of alkynes with various alcohols in the presence of iron salts (FeCl3 and FeBr3) was described to yield the corresponding alkenyl halides with complete regioselectivity and highstereoselectivity. The reaction is high yielding and works under mild conditions. The iron salts act as Lewis acids and a source of halides. The reaction tolerates a wide variety of functional
在铁盐(FeCl3 和 FeBr3)的存在下,炔烃与各种醇的新颖、简单和直接的一锅反应被描述为产生具有完全区域选择性和高立体选择性的相应烯基卤化物。该反应收率高,反应条件温和。铁盐充当路易斯酸和卤化物源。该反应耐受多种官能团。值得注意的是,这种方法便宜、高效且环保。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2009)
