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.

NMR (CD2CI2): delta 20.04 (s, 1 H), 8.46 (d, J = 10 Hz, 1 H), 7.17 (t, J = 8 Hz, 1 H), 7.1 – 6.3 (b, 6 H), 6.40 (t, J = 7 Hz, 1 H), 6.21 (d, J = 8 Hz, 1 H), 6.1 – 5.7 (b, 2 H), 4.07 (septet, J = 6 Hz, 1 H), 3.7 – 3.3 (b, 8 H), 2.7 – 1.7 (b, 36 H), 1.48 (d, J = 6 Hz, 6 H). 13C NMR (CD2CI2): delta 289.16 (m, Ru=CH), 220.80, 148.12, 142.58, 139.0 – 135.0 (b, m), 134.43, 130.15 (b), 129.33, 119.53, 119.78, 70.08, 55.0 – 52.0 (b), 23.40, 21.46, 19.47, 20.0 – 18.0 (b).

With the complex challenges of chemical substances, we look forward to future research findings about (1,3-Dimesitylimidazolidin-2-ylidene)(2-isopropoxybenzylidene)ruthenium(VI) chloride

Application of 301224-40-8

As the rapid development of chemical substances, we look forward to future research findings about 301224-40-8

A common heterocyclic compound, the ruthenium-catalysts compound, name is (1,3-Dimesitylimidazolidin-2-ylidene)(2-isopropoxybenzylidene)ruthenium(VI) chloride,cas is 301224-40-8, mainly used in chemical industry, its synthesis route is as follows.

General procedure: Hoveyda-Grubbs 2nd generation catalyst (19mg; 0.03mmol) was added to a solution of dien 7 (100mg; 0.31mmol) and styrene (2.48mmol) in dichloroethane (5mL). The reaction mixture was heated at 80C for 5h. Then, another portion of H-G catalyst (19mg; 0.03mmol) was added and the reaction mixture was heated at 80C for additional 5h. Then, the solvent was evaporated and crude solid was purified by column chromatography on silica gel (mobile phase – 3% ethyl acetate in cyclohexane, Rf of products 0.18-0.25). In some cases, stated in each experiment, HPLC had to be used due to very close retention time of product and starting material (mobile phase – 0.5% ethyl acetate in cyclohexane).

As the rapid development of chemical substances, we look forward to future research findings about 301224-40-8
