Synthesis of Triple‐Stranded Diruthenium(II) Compounds

A series of ligands containing a 1,4-disubstituted 1,2,3-triazole unit have been used for the formation triple-stranded dinuclear Ru(II) complexes. In contrast to previously reported complexes labile metals, use inert enabled stereoisomeric mixtures diruthenium(II) be accessed. The chromatographic resolution enantiomers helicate more rigid 1,4-xylyl spacer was carried out on cellulose. ligand modified and as flexibility increased production isomeric detected; mesocate forms were separated when an n -propyl used. This pair diastereomers found exhibit photoconversion, unique observation compounds this type. Partial separation via achieved -butyl spacer, presence mesocate/helicate confirmed.
