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. 768-11-6, Name is 5-Bromobenzothiazole, molecular formula is C7H4BrNS. In a Article，once mentioned of 768-11-6, Safety of 5-Bromobenzothiazole
We report an efficient and functional group-tolerant method for the synthesis of substituted dihydropyrans, based on tandem Pd-catalyzed cyclization/coupling of delta-acetylenic beta-ketoesters with aryl halides. The reaction proceeds cleanly through 6-exo-dig oxocyclizaton mode, delivering products with very good yields and complete control of regio- and stereoselectivity. Due to mild conditions, the transformation offers exceptional tolerance of functionalities, including NHR, formyl, enolizable ketone, free OH and NH2 groups, as well as a range of N-heterocyclic moieties of potential biological relevance.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.Safety of 5-Bromobenzothiazole. In my other articles, you can also check out more blogs about 768-11-6
