C-C BOND FORMATION BY THE PHOTOINDUCED REACTIONS OF cis-DIALKYLCOBALT(III) COMPLEXES WITH BENZYL AND ALLYL BROMIDES

Article abstract of DOI:10.1246/cl.1985.1355

The photocleavage of cobalt-carbon bonds of cis-dialkylcobalt(III) complexes, cis-ClO4 (R=Me, Et, and PhCH2; bpy=2,2'-bipyridine), induces the selective C-C bond formation from benzyl and allyl bromides to yield 1,2-diphenylethane and 1,5 hexadiene, respectively.The monoalkylcobalt(II) complexes ⁺ formed by the photocleavage reactions are responsible for the selective reduction of benzyl and allyl bromides.
