A NOVEL TYPE OF PHOTOSUBSTITUTION OF [FAC-RE(BPY)(CO)3BR] (BPY = 2,2'-BIPYRIDINE) WITH P(OR)3 IN THE PRESENCE OF TRIETHYLAMINE - EFFICIENT FORMATION OF [RE(BPY)(CO)2[P(OR)3]2]+BR-
Photochemical ligand substitution of [fac-Re(bpy)(CO)3Br] with P(OEt)3 in the presence of triethylamine quantitatively gave [Re(bpy)(CO)2{P(OEt)3}3]+Br- without the intervention of a mono-substituted product.
