In a glovebox complex 16 (0.125 g, 0.200 mmol) was dissolved in dichloromethane (3 ml), resulting in a darkgreen solution. AgOCN (149.89 g/mol, 0.460 mmol, 0.0689 g, 2.3 eq.) was suspended in DMF (2 ml) and slowly added.The reaction mixture was stirred for 3.5 h at room temperature before it was filtered and the resulting brown-greensolution dried in vacuum. The residual was dissolved in toluene and the resulting solution was filtered and dried invacuum to give complex 17 as a brown foam (125 mg, yield = 98 %). 1 H NMR (400.13 MHz, C6D6): delta = 16.65 (s, 1 H),7.06 (d, J = 7.4, 2 H), 6.86 (s, 4 H), 6.67 (t, J = 7.4, 1 H), 6.22 (d, J = 8.3, 1 H), 6.12 (s, 2 H), 4.25 (sep, J = 6.1, 1 H),2.23 (s, 12 H), 1.86 (s, 6 H), 1.07 (d, J = 6.1, 6 H). Complex 17 was dissolved in THF (5 ml) and 2a (78 mg, 0.200 mmol)was added as a solid in small portions. Residual reactant was transferred into the reaction mixture as a solution/suspensionin THF (1.5 ml). After 2 h a dark green solution had formed. The mixture was stirred for another 70 hours before all volatiles were removed under reduced pressure. The residual was dissolved in a minimum amount of dichloromethane,and then pentane was slowly added, in such a way as to obtain two separate layers, which were allowed to diffuse slowly(one week) into each other at -32C. The dark green crystals of 8a?CH2Cl2?C5H12 were isolated and washed three timeswith pentane and dried in the glovebox (82 mg, yield = 38 %).1H NMR (600.17 MHz, CD2Cl2): delta = 14.44 (s, 1 H, Ru=CH), 7.68-7.59 (br m, 2 H), 7.59-7.50 (br m, 3 N), 7.46-7.41 (m,2 H), 7.38-7.30 (m, 3 H), 7.27-7.21 (m, 1 H), 7.18 (br d, J = 1.9, 1 H), 7.05-6.97 (br m, 3 H), 6.95 (s, 2H), 6.90-6.70 (brm, 8 H), 6.60 (br dd, J = 7.5, 1.5 Hz, 1 H), 6.54 (br d, J = 8.3, 1 H), 4.25 (sep, J = 6.1 Hz, 1H), 2.41 (s, 6H), 2.13 (s, 6H),1.97 (s, 6H), 0.94 (d, J = 6.1 Hz), 0.59 (d, J = 6.1 Hz). 13C{1H} NMR (150.91 MHz, CD2Cl2): delta= 272.51, 272.48, , 175.90,153.92, 149,22, 147,26, 145,54, 145.17, 142.73, 141.54, 141.03, 139.19, 137.57, 137.30, 137.15, 136.07, 131.70,131.19, 129.28, 129.05, 128.98, 128,82, 128,56, 128.32, 127.84, 127.72, 127.60, 127.26, 126.98, 126.91, 125.63,124.96, 122.79, 122.16, 113.11, 76.29, 21.26, 21.07, 20.70, 19.77, 18.51.
