RuCl2 (PPh3) 3 (800 mg, 0.83mmol) and (1R, 2R) -1, 2-diphenylethylenediamine (195 mg, 0.92 mmol) are weighed and charged into a 20-mL Schlenk flask. The flask was reduced pressure to degas therein and then nitrogen gas was introduced into the flask. Dichloromethane (8 mL) was added thereto through a syringe, and the mixture was stirred under nitrogen atmosphere at room temperature for 3 hours. The reaction solution was then Celite-filtered, and the Celite layer was washed with dichloromethane (2mL). The filtrate obtained was concentrated under reduced pressure to a volume of about 2 mL; hexane (16 mL) was added thereto; and the mixture was stirred at room temperature for 1 hour. The precipitate was collected by filtration under nitrogen atmosphere, and the powder obtained was dried under reduced pressure (1 mmHg), to give 531 mg of a desired product (yield: 70%).

General procedure: The same basic method, as described here for [RuCl(PPh3)2(LMe,H)]Cl, was followed for all the complexes in this study. Asuspension of [RuCl2(PPh3)3] (0.36 g, 0.4 mmol) and LMe,H (0.15 g,0.4 mmol) in dry dichloromethane (15 cm3) was stirred for 3 h atroom temperature. This yielded an orange precipitate, which wascollected by filtration. Alternatively, the products 3-6 were solublein the reaction mixture, and were precipitated from it by careful addition of diethyl ether. In either case, the resultant solids werewashed repeatedly with diethyl ether to remove excess PPh3, thendried in vacuo.

The synthetic route of 15529-49-4 has been constantly updated, and we look forward to future research findings.
