Abstract

The utility of Suzuki cross-coupling methodology for the in situ elaboration of bromo- functionalised bis-terpyridyl iridium (III) complexes has been explored. The complex [Ir (tpy)(tpy-ϕ-Br)] 3+{tpy-ϕ-Br= 4′-(4-bromophenyl)-2, 2′: 6′, 2 ″-terpyridine} undergoes palladium-catalysed cross-coupling with aryl boronic acids to yield biaryl-substituted complexes directly. The biphenyl and 4-cyanobiphenyl-substituted products display ...
