摘要：

Regio- as well as stereospecific cis-reductions of a wide variety of acetylenic derivatives can be carried out in absolute ethanol with zinc powder activated with 1,2-dibromoethane and with zinc powder treated successively with dibromoethane and lithium bromocuprate, the first reagent being less powerful and more selective than the second one.
