An expeditious and highly practical, microwave assisted benzylation of naphthols and 4-hydroxycoumarin has been developed under catalyst-free & solvent-free conditions. Alcohols undergo heat induced dehydration to form ethers, which collapse reversibly to form the carbocation which was captured immediately by a suitable nucleophile to furnish the benzylated compounds.
transformation of CO bonds through a multistep reaction pathway in one pot. Electrolysis of the acidic reaction mixture significantly improved carbonyl reduction and thus facilitated the generation of benzyl carbocations, which show high reactivity towards electron-rich heteroarenes for C–C bond formation.
三氟甲磺酸/硅烷作为协同还原剂,可以通过多步反应途径在一锅中方便地转化 C O 键。酸性反应混合物的电解显着改善了羰基还原,从而促进了苄基碳阳离子的产生,其对富电子杂芳烃具有高反应性,可形成 C-C 键。
