Regio-as well as stereo-specific reductions of a wide variety of acetylenic derivatives have been carried out in absolute ethanol with zinc powder activated with 1,2-dibromoethane, and with zinc powder activated successively with dibromoethane and copper(I) bromide, the first reagent less powerful and more selective than the second one.
在无水乙醇中,用1,2-二溴乙烷活化的锌粉,以及依次用二溴乙烷和溴化铜(I)活化的锌粉,进行了多种炔属衍生物的区域还原和立体特异性还原。与第二种试剂相比,第一种试剂的功能更弱,选择性更高。
