摘要:Abstract(#br)KF/Al2O3 efficiently catalyzes N‐alkylation of heterocyclic, primary, and secondary amines and S‐alkylation of thiols with a variety of alkyl halides. The N‐alkylation and S‐alkylation adducts were produced in good to excellent yields...

摘要:... Direct mono‐ N ‐alkylation of primary benzylamines and anilines with a wide range of alkyl halides is promoted by a cesium base in the absence of any additive or catalyst. The basicity and solubility of cesium carbonate in anhydrous N , N ‐dimethylformamide not only...

摘要:Abstract(#br)The direct N‐alkylation of amines with alcohols was performed with an Ir‐Zr‐based metal–organic framework multifunctional heterogeneous catalyst. This system is efficient and environmentally benign for the synthesis of various organic amines in air in the ab...

摘要:Abstract(#br)The N‐alkylation of 2‐aminobenzonitriles with pyridyl methanols as the alkylating reagents has been demonstrated by using an easily available Ru3(CO)12/Binap/ t BuOK [Binap=2,2′‐bis(diphenylphosphino)‐1,1′‐binaphthyl] catalyst sy...

摘要:Abstract(#br)Possibly because homogeneous palladium catalysts are not typical borrowing hydrogen catalysts and ligands are thus ineffective in catalyst activation under conventional anaerobic conditions, they had not been used in the N‐ alkylation reactions of amines/amides wi...

摘要:Abstract(#br)A new approach to synthesize N ‐alkylation of azoles by iron(III)‐catalyst under solvent‐free conditions was developed. The method is broad in scope and highly efficient.

摘要:... In this paper, we report, for the first time, the N ‐alkylation reaction of electron deficient tetrazolopyridines. The treatment of tetrazolopyridines 5–13 with one equivalent of trialkyloxonium tetrafluoroborate leads to a mixture of two isomers, i.e. N3‐ and N2...

摘要:Abstract(#br)The enantioselective N‐alkylation of indole and its derivatives with aldimines is efficiently catalyzed by a zinc‐ProPhenol dinuclear complex under mild conditions to afford N‐alkylated indole derivatives in good yield (up to 86 %) and excellent enantiomeric...
