Benzylidenebis(tricyclohexylphosphine)dichlororuthenium, cas is 172222-30-9, it is a common heterocyclic compound, the ruthenium-catalysts compound, its synthesis route is as follows.,172222-30-9
A suspension of 3.07 g (3.73 mmol) of [RuCl2(PCy3)2(phenylmethylene)] (commercial available from Sigma-Aldrich Inc., St. Louis, USA), 380 mg (3.84 mmol) copper chloride and 1.06 g (4.10 mmol) 4-chloro-2-trifluoromethyl-8-vinyl-quinoline in 135 ml methylene chloride was stirred at 300C for 90 min. The reaction mixture was evaporated to dryness and the isolated crude product purified by silica gel chromatography (hexane / ethyl acetat 2:1) and finally digested in 50 ml pentane at room temperature for 30 min to yield 429 mg (17percent) of the title compound as dark green crystals. MS: 697.0 (M+). 31P-NMR (121 MHz, C6D6): 54.2 ppm. 1H-NMR (300 MHz, C6D6): 1.18-2.35 (m, 30H); 2.60 (q, J=12.0Hz, 3H); 6.82 (t, J=6.0Hz, IH); 7.01 (d, J=3.0Hz, IH); 7.55 (d, J= 6.0Hz, IH); 7.89 (d, J=6.0Hz, IH); 17.80-17.90 (m, IH).
With the rapid development of chemical substances, we look forward to future research findings about Benzylidenebis(tricyclohexylphosphine)dichlororuthenium
