YieldReaction ConditionsOperation in experiment
75% With potassium <i>tert</i>-butylate In hexane at 60℃; for 24 h; Schlenk technique RuCl2(═CHPh)(PCy3)s (phenylmethylene-bis(tricyclohexylphosphine) ruthenium dichloride, “catalyst (I)”) (6.00 g, 7.29 mmol, 1.0 eq.), IMesH2.HCl salt prepared above (2 eq.), and potassium t-butoxide (2 eq.) were placed in a Schlenk flask. 60 mL of anhydrous degassed hexanes (Aldrich SureSeal bottle) were added. A vacuum was applied to further degas the reaction mixture, which was then heated to 60° C. for 24 hours. The suspension changed color from purple to orange-brown over the reaction time. After approximately 24 hr, the mixture was cooled to room temperature, and an excess of 1:1 isopropanol:water (180 mL) was added. The mixture was stirred rapidly in air for 30 min., then filtered using a medium porosity frit, and washed with isopropanol-water (3×100 mL) and hexanes (3×100 mL). The solids were dried in in vacuo, and the yield was approximately 75percent. 1H NMR (CD2Cl2, 400 MHz) δ 19.16 (s, 1H), 7.37-7.05 (m, 9H), 3.88 (s, 4H), 2.56-0.15 (m, 51H); 31P NMR (CD2Cl2, 161.9 MHz) δ 31.41; HRMS (FAB) C45H65Cl2N2PRu [M+] 848.3306, found 848.3286.
