(0104) Even if both of the catalysts possess two 5,7-dichloro-8-hydroxyquinolines, they show different NMR patterns. The different structures were revealed by X-ray diffraction. The crystals for the X-ray diffraction measurement were obtained by slow diffusion of Et2O in a saturated solution of CH2Cl2. The two derivatives exhibit a different geometry considering the 8-quinolinolate substituents. In derivative 3, the oxygen atoms of the two quinolinolates are orientated trans to each other, while in derivative 4 these trans positions are occupied by an oxygen and a nitrogen atom of the two different quinolinolates.

301224-40-8, cis-RuC12(slMes)( CHC6H4O1-Pr)(PhP(OMe)2), cis-C797: To a round-bottomed flask was charged C627 (15.0 g), degassed CH2C12 (1000 mL) and a magnetic stir bar under nitrogen, followed the addition of phosphonite PhP(OMe)2 (4.1 g). The solution was stirred for 3.7 h and second portion of phosphonite PhP(OMe)2 (2.05 g) was added. The solution was continued to stir for 2 more hours and the solution was concentrated by a rotary evaporator. A silica gel plug column (4 x 2.5 in, D x H) was pre-wetted with CH2C12. Low vacuum suction was used to assist elution. The crude was loaded on the top of the column. The first eluent was CH2C12 and a green fraction was collected, that was C627 as verified by NIVIR. The green fraction was followed by a yellow fraction that appeared to be an oxidation derivative of the phosphonite. The eluent was then switched to gradient mixture of CH2C12 /EtOAc. A brown band containing the product was collected. The solvent was removed by a rotary evaporator and the residue was recrystallized from CH2C12 /heptanes. black crystalline solid was obtained (3.1 g). ?H NMR (400 IVIHz, CD2C12, ppm): oe 15.83 (d, J = 24 Hz, 1H, Ru=CI]), 9.16 (dd, J = 8 Hz, J = 2 Hz, 1H), 7.51 (m, 1H), 7.25 (m, 1H), 7.15 (m, 2H), 7.02 – 6.88 (m, 5H), 6.66 (s, 1H), 6.61 (d, J = 8 Hz, 1H), 6.14 (s, 1H), 4.49 (septet, J = 6Hz, 1H, CIJMe2), 4.02-3.62 (m, 4H, CH2CH2), 3.33 (d, J = 11 Hz, 3H, OCH3), 3.05 (d, J = 12 Hz, OCH3), 2.67 (s, 3H, mestyl methyl), 2.62 (s, 3H, mestyl methyl), 2.46 (s, 3H, mestyl methyl), 2.33 (s, 3H, mestyl methyl), 2.22 (s, 3H, mestyl methyl), 1.95 (s, 3H, mestyl methyl), 1.46 (d, J = 6Hz, 3H, CH(CH3)2), 1.19 (d, J = 6Hz, 3H, CH(CH3)2).3?P NIVIR (161.8 IVIFIz, CD2C12, ppm): oe 163.84 (b).

Hoveyda-Grubbs second generation catalyst H2 (104 mg, 0.16 mmol) and potassium 2,6-dimethylbenzenethiolate (34 mg, 0.19 mmol) 2b were transferred to a 25 mL Schlenk flask, followed by addition of 4 mL of toluene and 1 mL THF under argon. Then the mixture was stirred vigorously at 20 C. for 30 min. During this time the color of the mixture turned from light green to a slightly darker green.
