Reaction de metathese des olefines induite photochimiquement en presence d'un complexe de metal de transition: III. Caracterisation generale de la transformation

Activated sodium hydride (NaHRONa) was treated with Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Cd, Zr, Mo, Pd, W salts to give the new complex reducing agents NaHRONaMX_n (CRA). Their reactivities were examined for reduction of 1-bromonaphthalene. In most cases, the CRA exhibited very good reducing abilities, which can be varied by changing the solvent, the alkoxide, or the temperature. Moreover, some CRA act as coupling agents for aromatic halides. Easy to prepare and handle on a preparative scale, CRA must be regarded as very promising tools for organic synthesis.
