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. 33100-27-5, Name is 1,4,7,10,13-Pentaoxacyclopentadecane, molecular formula is C10H20O5. In a Article，once mentioned of 33100-27-5, Formula: C10H20O5
Treatment of the Zn-Zn-bonded compounds [L2-Zn-ZnL 2-]· [M(THF)2]2 (1a, M = Na; 1b, M = K; L = [(2,6-iPr2C6H3)NC(Me)]2), which contain doubly reduced alpha-diimine ligands, with 15-crown-5 and 18-crown-6 led to the ion-separated compounds [L2-Zn-ZnL2-]· [Na(15-crown-5)(THF)2]2 (2a), [L2-Zn-ZnL 2-]· [K(15-crown-5)2]2·4THF (2b), and [L2-Zn-ZnL2-]· [K(18-crown-6)(THF) 2]2·2THF (2c). In the products, the alkali metal ions originally bound by the ligands have been captured by the crown ethers. The Zn-Zn bond distances in 2a, 2b, and 2c are longer than those in the corresponding parent compounds 1a and 1b and in an analogous compound, [L -Zn-ZnL-] (3), bearing the monoanionic alpha-diimine ligands. Theoretical computations suggested that the Zn-Zn bonds in 2a-c are less stable than those in 1a and 1b. Reactions of [L-Zn-ZnL -] (3) with different amounts of PhC?CH afforded the dimeric product [L-Zn(nu-C?CPh)]2 (4) and the monomeric [L0Zn(C?CPh)2]·2THF (5), respectively, while the reaction of the crown ether-containing compound 2b with PhC?CH gave a homoleptic zinc alkynide, [Zn(C?CPh)4]·[K(15-crown-5) 2]2·THF (6).
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.Formula: C10H20O5, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 33100-27-5, in my other articles.
