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. 14187-32-7, Name is Dibenzo-18-crown-6, molecular formula is C20H24O6. In a Article，once mentioned of 14187-32-7, name: Dibenzo-18-crown-6
Abstract Directed by potassium-crownether host-guest cation, a unique octameric eicosanuclear heterothiometallic Mo/S/Cu cluster [K(dibenzo-18-crown-6)(DMF)2]4[Mo8S32Cu12] (1) was synthesized by the reaction of (NH4)2MoS4, CuI, KI, dibenzo-18-crown-6 in DMF solution. 1 was characterized by elemental analysis, IR, thermogravimetric analysis, X-ray powder and single crystal diffractions. 1 crystallizes in the tetragonal space group I41cd. The anionic octameric eicosanuclear [Mo8S32Cu12]4- cluster exhibits a supra-cubane-like skeleton, fabricated by four nest-shaped clusters [Mo(mu1-S)(mu3-S)3Cu3]+ and four flywheel-shaped clusters [Mo(mu2-S)3(mu4-S)Cu3]+ linking together through shared Cu atoms. The cation [K(dibenzo-18-crown-6)(DMF)2]+ of 1 exhibits the host-guest configuration, where K+ is embedded in the center of dibenzo-18-crown-6. Furthermore, Z-scan studies (532 nm, 21 ps pulses) reveal that 1 possesses effective third-order nonlinear optical (NLO) properties.
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.name: Dibenzo-18-crown-6, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 14187-32-7, in my other articles.
