15529-49-4, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. Dichlorotris(triphenylphosphino)ruthenium (II), cas is 15529-49-4,the ruthenium-catalysts compound, it is a common compound, a new synthetic route is introduced below.

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)
