Abstract

Two cycloruthenated complexes of formulation $[(\eta^6$-p-cymene)RuCl(L)], where L=(phenylazo)phenyl (pap) (1a) and $(4,4^{\prime}$-dimethyl)(phenylazo)phenyl (dmpap) (1b) were prepared from a transmetallation reaction involving $[(\eta^6$-p-cymene)$RuCl_2]_2$ and [HgCl(L)] in refluxing $CHCl_3$ or MeOH. The molecular structure of $[(\eta^6$-p-cymene)RuCl(pap)] (1a) has been determined by X-ray crystallography. The complex contains a $[(\eta^6$-p-cymene group, a chloride and a bidentate C,N-donor orthometallated (phenylazo)phenyl ligand. The complexes have been characterized from NMR data. The orthometallated carbon appears near \delta 188 ppm in the $^{13}C$-NMR in $CDCl_3$ .
