1.A process for the preparation of a di-, tri-, or tetra fluoroarylamine comprising at least the step of:a) amination of a di-, tri-, or tetra fluoroarylchloride in the presence ofi) ammonia,ii) at least one base,iii) at least one metal catalyst complexiv) at least one ligand, ...
Pd(II)-catalyzed intramolecular amination of arenes is developed using either a one- or two-electron oxidant. The reaction protocol tolerates a wide range of deactivating groups including acetyl, cyano, and nitro groups. This catalytic reaction allows expedient syntheses of broadly useful substituted ...

A Pd-catalyzed oxidative C–H amination of N-Ts-2-arylanilines under ambient temperature using Oxone as an inexpensive, safe, and easy-to-handle oxidant has been developed. This process represents a green and practical method for the facile construction of carbazoles with a broad substrate scope...
摘要: We describe the first Pd catalyzed method for the one-step C H amination of simple arenes. The activity of the catalysts is highly dependent on the Pd:ligand ratio and the identity of the used ligands. Turnover numbers up to 12 can be achieved....
