trans-RuC12(slMes)(CHPh)(Ph2P(OMe)), trans-C785: trans-C727 (4.35 g, 6.0 mmol) was dissolved in degassed CH2C12 (50 mL) with a magnetic stir bar under nitrogen in a round-bottomed flask. The flask was capped with a gas adaptor. Methyl diphenylphosphinite (2.6 g, 12 mmol) was syringed to the flask under nitrogen flow. The green solution turned brown immediately, which was continued to stir at room temperature for lh. The lights were removed under high vacuum, yielding a mixture of black oil and brown crystalline material. The flask was chilled by liquid nitrogen and the resulting solid was broken into small pieces with a spatula. Hexanes (50 mL) was added and the solvent was reduced by a rotary evaporator. The pink solid was collected by a frit funnel with vacuum filtration and washed with hexanes twice (2 x 25 mL). The solid was dried under high vacuum for 16h. Yield: 2.91g (62%). ?H NIVIR (400 IVIHz, C6D6, ppm): oe 19.33 (s, 1H, Ru=CH), 7.86 (d, J = 8 Hz, 2H), 7.33 (m, 4H), 7.13 (t, J = 8 Hz, 1H), 7.10 – 6.88 (m, 6H), 6.83 (s, 2H), 6.80 (m, 2H), 6.32 (s, 2H), 3.46 – 3.38 (m, 2H), 3.34 – 3.25 (m, 2H),3.29 (d, J = 12Hz, 3H), 2.79 (s, 6H), 2.39 (s, 6H), 2.17 (s, 3H), 1.90 (s, 3H). 3?P NIVIR (162 IVIHz, C6D6, ppm): oe 132.5 (s).
