## Abstract Achiral P‐donor pincer‐aryl ruthenium complexes ([RuCl(PCP)(PPh~3~)]) 4c,d were synthesized __via__ transcyclometalation reactions by mixing equivalent amounts of [1,3‐phenylenebis(methylene)]bis[diisopropylphosphine] (2c) or [1,3‐phenylenebis(methylene)]bis[diphenylphosphine] (2d) and
w Ž . x X Reaction of RuCl p-cymene with the tridentate N-N -N ligands, 2,6-pyridyl-diimines, led to substitution of 2 2 p-cymene. The resulting complexes, believed to be coordinatively unsaturated, exhibit efficient activity for the epoxidation Ž . of cyclohexene in the presence of iodosobenzene P
