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. 250285-32-6, Name is 1,3-Bis(2,6-diisopropylphenyl)imidazolium chloride, molecular formula is C27H37ClN2.

Iron-catalyzed coupling of aryl sulfamates and aryl/vinyl tosylates with aryl grignards
The iron-catalyzed coupling of aryl sulfamates and tosylates with aryl Grignard reagents is reported for the first time. The methodology employs air-stable, low-cost FeF3¡¤3H2O and the N-heterocyclic carbene ligand IPr¡¤HCl as the preligand to form a long-lived catalyst upon treatment with aryl Grignards. The reaction provides a range of cross-coupled products in good-to-excellent yields. In contrast to previous reports with aryl chlorides, these reactions proceed with low levels of Grignard homocoupling regardless of the iron source.
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.SDS of cas: 250285-32-6, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 250285-32-6, in my other articles.
