Wei, Dong published the artcileSynthesis of Substituted Naphthalenes by 1,4-Palladium Migration Involved Annulation with Internal Alkynes, SDS of cas: 74317-85-4, the main research area is naphthalene preparation; alkyne bromo vinylbenzene palladium migration annulation.
The palladium catalyzed annulation of 1-bromo-2-vinylbenzene derivatives with internal alkynes was realized for the efficient synthesis of substituted naphthalenes such as I [ R1 = Me, 2-thienyl, Ph, etc.; R2 = 7-Me, 7-OMe, 7-F, etc.; R3 = R4 = Me, 2-thienyl, Ph, etc.]. A controllable aryl to vinylic 1,4-palladium migration process was the key for success of this transformation. A wide variety of substituted naphthalene compounds were prepared in good to excellent yields.
Chinese Journal of Chemistry published new progress about Alkynes, internal Role: RCT (Reactant), RACT (Reactant or Reagent). 74317-85-4 belongs to class bromides-buliding-blocks, name is 2-Bromo-4-methoxybenzoic acid, and the molecular formula is C8H7BrO3, SDS of cas: 74317-85-4.
