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–
Abstract
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.
