Since a few years, considerable attention has been devoted to the study of reducing agents which consist of mixtures of transition metal salts and metal hydrides\*. When we started our works on this subject, sodium hydride had scarcely been used for the preparation of this kind of reagents. In previ
Vinyl halides can be coupled by NiCRA-bpy in THF or hexane. Interestingly simply changing the solvent changes the nature of the product : diene in THF, and enyne in hexane. Metal promoted homocoupling of vinyl halides continues to be actively studied on account of its wide range of synthetic applic
Our previous publications showed that Complex Reducing Agents (CM) NaH-RONa-MXn (where RONa was a sodium alcoholate and MXn Ni, Co ~37 salts) are new cheap, easily prepared
Reduction of carbon-carbon double bonds can be achieved with either NiCRA or NiCRASi (nickel containing Complex Reducing Agent activated by Me3SiCl). Selective reduction of polyunsaturated hydrocarbons or unsaturated ketones are easily performed with both reagents.
