In(OTf)3 catalyzed N-benzylation of amines utilizing benzyl alcohols in water
摘要:
An In(OTf)(3)-catalyzed N-benzylation of amines utilizing benzyl alcohols through direct C-O bond activation has been reported. The reaction was performed in water without any base, additive, ligand or inert gas protection to afford the chem-selective mono- or bis-alkylated aromatic amines in good to excellent yields.

Novel para-[aryl(alkyl or alkenyl)amino]benzoic acids, esters, pharmaceutically acceptable salts and pharmaceutical compositions thereof and a method of lowering serum lipid levels in mammals therewith.
Various tertiary benzanilide derivatives were effectively synthesized from substituted benzoic acid and N-monoalkylated aniline using dichlorotriphenylphosphorane in chloroform. Yields were generally high, even when an electron-withdrawing group substituted the aromatic ring of aniline, or when an electron-donating group substituted the aromatic ring of benzoic acid.

Exogenous photocatalyst-free, single nickel-catalyzed carbon–heteroatomcoupling under visible-light irradiation is reported. Over 15 classes of nucleophile can efficiently couple with aryl/alkene halides to afford valuable heteroatomic arenes/alkenes. The unprecedentedly broad substrate scope and late-stage modification of valuable molecules fully demonstrate the benefits of the method.
