The article was titled 《Ni-Catalyzed Arylbenzylation of Alkenylarenes: Kinetic Studies Reveal Autocatalysis by ZnX2》.Category: bromides-buliding-blocks The article contains the following contents:
We report a Ni-catalyzed regioselective arylbenzylation of alkenylarenes with benzyl halides and arylzinc reagents. The reaction furnishes differently substituted 1,1,3-triarylpropyl structures that are reminiscent of the cores of oligoresveratrol natural products. The reaction is also compatible for the coupling of internal alkenes, secondary benzyl halides and variously substituted arylzinc reagents. Kinetic studies reveal that the reaction proceeds with a rate-limiting single-electron-transfer process and is autocatalyzed by in-situ-generated ZnX2. The reaction rate is amplified by a factor of three through autocatalysis upon addition of ZnX2. The experimental part of the paper was very detailed, including the reaction process of Methyl 3-(bromomethyl)benzoate(cas: 1129-28-8Category: bromides-buliding-blocks)
Methyl 3-(bromomethyl)benzoate(cas: 1129-28-8) belongs to organobromine compounds.The reactivity of organobromine compounds resembles but is intermediate between the reactivity of organochlorine and organoiodine compounds. Dehydrobromination, Grignard reactions, reductive coupling, Wittig reaction, and several nucleophilic substitution reactions are some of the principal reactions which involve organic bromides.Category: bromides-buliding-blocks
