15529-49-4, Dichlorotris(triphenylphosphino)ruthenium (II) is a ruthenium-catalysts compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
RuCl2(PPh3)3 (1 g, 1 .04 mmol) and the ligand of formula (IVg) (obtained from Example 1 ) (231 .4 mg, 1 .1 mmol) were placed in a 25 mL Schlenk tube under argon atmosphere, and dissolved in dry diglyme (2 mL). The reaction mixture was heated to 165C for 2 h, allowed to cool down to room temperature and stored at -18C to precipitate further overnight. Cold Et2O (2 mL) was added while cooling with a dry ice//so-propa- nol bath. The precipitate was filtrated by cannula, and washed with Et2O (5 times 2 mL). The orange powder was dried in vacuo, affording 530 mg (79%) of Ru(6-MeNN- SEt)(PP i3)Cl2 as an orange powder. An equilibrium of two conformations of Ru(6- MeNNSEt)(PPh3)Cl2 are existent in solution, delivering a doubled set of signals in NMR. For 1H-NMR only data of the major conformation is given due to overlapping signals. 1H-NMR (300 MHz, CD2CI2): delta 7.67-7.16 (m, 17H, CHarom), 7.01 (d, 1 H, J = 7.8, CHarom), 5.65 (m, 2H), 4.47 (m, 1 H), 3.5 (m, 1 H), 3.34 (m, 1 H), 3.22 (d, 1 H, J = 1 1 .1 ), 2.98 (m, 1 H), 2.59 (m, 1 H), 1 .53 (m, 2H), 0.87 (t, 3H, J = 7.5) ppm. 31P-NMR (122 MHz, CD2CI2): delta 48.8, 45.8 ppm. HRMS (ESI+): calculated for C29H32CI2N2PRUS (M+H): 644.0518; found 644.0518 (M+H), 667.0412 (M+Na)
15529-49-4, The synthetic route of 15529-49-4 has been constantly updated, and we look forward to future research findings.
