cis-RuC12(slMes)(CHC6H4O1-Pr)(Ph2P(OMe)), cis-C843: C627 (35.0 g, 56 mmol) was dissolved in degassed CH2C12 (2000 mL) in an 1-neck round-bottomed flask under nitrogen, to which methyl diphenylphosphinite (50 g, 231 mmol) was syringed. The flask was connected to a Friedrich condenser, which was in turn attached to vacuum/nitrogen line. The mixture was degassed by vacuum/nitrogen 3-times. An oil bath was used to heat the flask. The oil bath temperature was kept at 50 C for 40 h and then cooled to room temperature. The solvent was removed under high vacuum. The residue was dissolved in a minimum amount of CH2C12 and loaded on top of Si02 gel column (4 x 3 in, D x H) and eluted with CH2C12. A red band which stuck on column was rinsed down by methanol. The solvent was removed by rotary evaporator and a green solid was obtained. The solid was further purified by recrystallization from CH2C12 /Hexanes.

General procedure: In a glove box, a flask was charged with Ru complex 4 or 5 and Ag salt 3. Anhydrous degassed CH2Cl2 was then added and the resulting mixture was stirred at room temperature for 3h in the dark. The solids were filtered off through a Celite layer and washed with anhydrous (2mL). The solution was diluted with anhydrous hexane (10mL) and remaining precipitated Ag salt was again filtered off. Evaporation of the solvents on a rotary vacuum evaporator (40C, 1h, 25kPa) and finally at oil pump vacuum (25C, 1h, 1kPa) gave the products 1 or 2.
