A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 301224-40-8, Name is (1,3-Dimesitylimidazolidin-2-ylidene)(2-isopropoxybenzylidene)ruthenium(VI) chloride, molecular formula is C31H38Cl2N2ORu. In a Article£¬once mentioned of 301224-40-8, COA of Formula: C31H38Cl2N2ORu
Ionically tagged ru-alkylidenes for metathesis reactions under biphasic liquid-liquid conditions
The synthesis of the novel ionic Ru-alkylidenes [Ru[(4-CO2)(1-CH3)Py+)]2(IMesH2)(=CH-2-(2-PrO)-C6H4)][OTf-]2 (1, IMesH2=1,3-dimesitylimidazolin-2-ylidene, Py=pyridine, OTf-=triflate) and [RuCl[(4-CO2)(1-CH3)Py+)](IMesH2)(=CH-2-(2-PrO)-C6H4)][OTf-] (2) is reported. Catalysts 1 and 2 were successfully used in various metathesis reactions under biphasic liquid-liquid conditions using 1-butyl-2,3-dimethylimidazolium tetrafluoroborate and heptane as liquid phases. Ruthenium leaching into the heptane phase was very low (<0.4%), translating into Ru contamination of the products between 0.3 and 2.5ppm. Both 1 and 2 exhibited comparable reactivity in organic solvents and under biphasic conditions. Catalyst 1 and 2 were also successfully used in the continuous metathesis of methyl oleate and 1,7-octadiene under supported liquid-liquid conditions. Finally, the disproportionation of the monocarboxylato monochloro substituted Ru-alkylidene 2 was traced by 1HNMR analysis at 40C, thereby demonstrating the formation of complex 1 and the neutral complex [RuCl2(IMesH2)(=CH-2-(2-PrO)-C6H4)]. Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.COA of Formula: C31H38Cl2N2ORu.
