Efficient Nickel-Mediated Intramolecular Amination of Aryl Chlorides
摘要:
[GRAPHICS]The use of an in situ generated Ni(0) catalyst associated with 2,2'-bipyridine or N,N'-bis(2,6-diisopropylphenyl)dihydroimidazol-2-ylidene (SIPr) as a ligand and NaO-t-Bu as the base for the intramolecular coupling of aryl chlorides with amines is described. The procedure has been applied to the formation of five-, six-, and seven-membered rings.

The first transition-metal-free catalytic protocol for controlled reduction of amide functions using cheap and bench-stable hydrosilanes as reducing agents has been established. By altering the hydrosilane and solvent, the new method enables the selective cleavage of unactivated C-O bonds in amides and allows the C-N bonds to selectively break via the deacylated cleavage. Overall, this novel process

A rhodium(III)-catalyzed C–C coupling between 2-vinyloxiranes and arenes directed by different chelating groups has been realized via a C–Hactivation pathway. This reaction proceeded under conditions with a low catalyst loading, and allylic alcohols were isolated as the coupling products. A series of benzoazepanes has been synthesized by following this coupling.
