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, Product Details of 14187-32-7
Four supramolecular cations (m-XAni+)(DB[18]crown-6) (X = F, Cl, Br or I; Ani+ = anilinium ion; DB[18]crown-6 = dibenzo[18]crown-6) were introduced into crystals of a Keggin [SMo12O402-] polyanion to form [(m-XAni+)(DB[18]crown-6)]2[SMo12O402-]·4CH3CN (1, 2, 3 or 4 for X = F, Cl, Br or I) through a hydrogen-bonding interaction. Crystals 1, 2, 3 and 4, which were isomorphous to each other, crystallized in the monoclinic space group P21/n. Supramolecular cations (m-XAni+)(DB[18]crown-6) were constructed by a N-H+…O hydrogen-bonding interaction. [SMo12O402-] polyoxoanions were infinitely extended in three dimensions through a weak C-H…O hydrogen-bonding interaction with DB[18]crown-6. Disorder of the halogen atoms at the meta-position was observed in crystals 1, 2 and 3. The rotational freedom of the (m-XAni+) cations was suppressed because of weak interactions with surrounding molecules.
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.Product Details of 14187-32-7, 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.
