The palladium catalysed Miyaura cross-coupling reactions of 4?-(4-bromophenyl)-2,2?:6?,2?-terpyridine (tpy-phi-Br) and 4?-bromo-2,2?:6?,2?-terpyridine (tpy-Br) with bis(neopentyl glycolato)diboron (B2neo2 lead to the first reported examples of boronate ester-substituted terpyridine ligands, L1 and L2. Ligand L1, which incorporates a benzene ring between the terpyridine group and the boron, reacts with transition metals such as iron and ruthenium to generate complexes containing the analogous boronic acid-substituted terpyridine L3. The heteroleptic complex [Ru(ttpy)L3]2+ has also been prepared by an analogous cross-coupling reaction of the bromo complex [Ru(ttpy)(tpy-phi-Br)]2+ with B2neo2 (ttpy =4?-tolyl-2,2?:6?,2?-terpyridine). The structurally related complex [Ru(ttpy)L4]2+ (L4 = terpyridine-4?-boronic acid) could not be prepared, either directly from L2 or from [Ru(ttpy)(tpy-Br)]2+, apparently due to competitive hydrodeboration and solvolysis. The complex [Ru(ttpy)L3]2+ reacts with aryl halides under standard palladium-catalysed Suzuki-Miyaura cross-coupling conditions to generate more elaborate 4?-aryl-substituted terpyridyl complexes. Cross-coupling has also been achieved by reaction of [Ru(ttpy)(tpy-Br)]2+ with an arylboronic acid. The photophysical properties of [Ru(ttpy)L3]2+ are shown to be largely typical of ruthenium bis-terpyridyl complexes.
