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 power treated successively with dibromoethane and lithium bromocuprate, the first reagent being less powerful and more selective than the second one.

Preparative-scale heterogeneous hydrogenation over Nic at room temperature and 1 atm are described.It is shown that these catalysts allow the selective hydrogenation of carbon-carbon double bonds in the presence of oxo groups without side reactions.Alkynes and functional alkynes are selectively hydrogenated to the corresponding cis alkenes in high yields.Carbonyl group hydrogenations were also performed in high yields.Selective hydrogenation properties of Nic were exemplified in the steroid series.Finally, it was demonstrated that this new catalyst-preparation concept is not limited to nickel and also applies to the preparation of cobalt and palladium catalysts.
