Synthesis and characterisation of new pyrazole–phosphinite ligands and their ruthenium (II) arene complexes

The new potentially bidentate pyrazole–phosphinite ligands [(3, 5-dimethyl-1H-pyrazol-1-yl)
methyl diphenylphosphinite](L1) and [2-(3, 5-dimethyl-1H-pyrazol-1-yl) ethyl
diphenylphosphinite](L2) were synthesised and characterised. The reaction of L1 and L2
with the dimeric complexes [Ru (η6-arene) Cl2] 2 (arene= p-cymene, benzene) led to the
formation of neutral complexes [Ru (η6-arene) Cl2 (L)](L= L1, L2) where the pyrazole–
phosphinite ligand is κ1-P coordinated to the metal. The subsequent reaction of these …
