“…We note that extended heating of complexes containing 1 or 2 results in dehalogenation of the ligand, so particular care is required when performing coupling reactions upon these units. These building blocks were further elaborated with additional metal ion binding sites using Pd(0) cross-coupling reactions such as those we have described previously .…”

“…These building blocks were further elaborated with additional metal ion binding sites using Pd(0) cross-coupling reactions such as those we have described previously. 14 Specifically, reaction of [Ru(phen) 2 ( 1)](PF 6 ) 2 or [Ru(phen) 2 ( 2)](PF 6 ) 2 with excess 4-pyridineboronic acid pinacol ester, Pd(PPh 3 ) 4 , and Cs 2 CO 3 in degassed water/dimethylformamide (DMF) gave [Ru(phen) 2 ( 3)](PF 6 ) 2 and [Ru(phen) 2 ( 4)](PF 6 ) 2 with isolated yields of 71% and 73%, respectively (Schemes 1 and 2). Similarly, the reaction of [Ru(phen) 2 ( 1)](PF 6 ) 2 or [Ru-(phen) 2 ( 2)](PF 6 ) 2 with excess 4-ethynylpyridine, Pd(PPh 3 ) 4 , and CuI in degassed 1,2-dimethoxyethane (DME)/DMF/NEt 3 gave [Ru(phen) 2 ( 5)](PF 6 ) 2 and [Ru(phen) 2 ( 6)](PF 6 ) 2 with isolated yields of 60% and 54%, respectively (Schemes 1 and 2).…”

“…NMR spectroscopy showed evidence of ( 1-NO ) to ( 1 ) conversion (Figure ). NMR spectrum of ( 1 ) is well-known and has a distinct signal because of its D 3 point-group symmetry. The majority of the ( 1-NO ) converts to ( 1 ) in D 2 O after 30 min of 650 nm illumination (Figure ).…”
