General procedure: To a round-bottomed flask with a stir bar was placed with [Ru(PPh3)3Cl2] (868 mg, 2.0 mmol) under the nitrogen. Pre-dried THF(10 mL) was added and the resulting mixture was stirred at room temperature. Then salen-enH2 (536 mg, 2.0 mmol) and a little excess of Et3N (252 mg, 2.5 mmol) in THF (5 mL) were added. The reaction mixture was stirred at room temperature overnight. After removal of solvents, CH2Cl2 (15 mL) was added and the solution was filtered through cilite. The filtrate was concentrated and the residue was washed with Et2O (5mL 2) and hexane (5 mL 2) to give the desired product. Recrystallization from CH2Cl2/Et2O (1:2) afforded green block-shaped crystals of [RuCl(PPh3)(salen)] (3) suitable for X-ray diffraction in three days. Yield: 1011 mg, 76% (based on Ru).

In a glove box, NHC ligand precursor 23 (63 mg, .13, mmol), ruthenium precursor 11 (78 mg, .13 mmol) and KOMJu(Fe) (29 mg, .13 mmol) were combined in toluene. The flask was sealed, removed from the glove box and stirred at 60 0C for 18 hours. The reaction was concentrated and purified by flash column chromatography (5% –> 20% Et2O/Pent). There were 3 bands that could be isolated from this column, first 2 brown bands and then one green band. The second brown band was the desired product; however, it was not completely pure after one column. Recolumning in 10% Et2O/Pentane gave a brown oil product completely pure by 1H NMR (9 mg, 9%) and another fraction still slightly impure (18 mg, 18%).
