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. 1436-59-5, Name is cis-Cyclohexane-1,2-diamine, molecular formula is C6H14N2. In a Article，once mentioned of 1436-59-5, Recommanded Product: cis-Cyclohexane-1,2-diamine
The reaction of (NH4)2[WS4] with (±)trans-1,2-diaminocyclohexane (trans-1,2-cn), bis(2-aminoethyl)amine (dien) and bis(3-aminopropyl)amine (dipn) leads to the formation of the organic ammonium tetrathiotungstates (trans-1,2-cnH)2[WS4] (1), (dienH2)[WS4] (2) and (dipnH2)[WS4] (3) [trans-1,2-cnH is (±)trans-2-aminocyclohexylammonium; dienH2 is 1,7-diazonia-4-aza-heptane; dipnH2 is 1,5-diazonia-9-aza-nonane] in good yields. The title complexes 1-3 react with [Ni(en)3]2+ (en = ethylenediamine) forming the highly insoluble complex [Ni(en)3][WS4]. The structure of the complexes 1-3 can be described as consisting of tetrahedral [WS4]2- dianions which are linked to the monoprotonated cation of trans-1,2-cn in 1 and the diprotonated cations of dien and dipn in 2 and 3, with the aid of weak hydrogen bonding interactions. The difference between the longest and the shortest W-S bond lengths Delta is 0.0104, 0.0170 and 0.0173 A? in 1, 2 and 3, respectively. A comparative study of the structural features of several tetrathiotungstates is presented and the interactions between the organic cations and the tetrathiotungstate anions are discussed in terms of the magnitude of Delta, the difference between the longest and the shortest W-S bond distances.
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.Recommanded Product: cis-Cyclohexane-1,2-diamine, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 1436-59-5, in my other articles.
