Nickel‐Catalyzed Reductive Alkylation of Heteroaryl Imines**
نویسندگان
چکیده
The preparation of heterobenzylic amines by a Ni-catalyzed reductive cross-coupling between heteroaryl imines and C(sp3) electrophiles is reported. This umpolung-type alkylation proceeds under mild conditions, avoids the pre-generation organometallic reagents, exhibits good functional group tolerance. Mechanistic studies are consistent with imine substrate acting as redox-active ligand upon coordination to low-valent Ni center. resulting bis(2-imino)heterocycle⋅Ni complexes can engage in reactions variety electrophiles, giving amine products yields.

Lithiated imines: solvent-dependent aggregate structures and mechanisms of alkylation.
We describe efforts to understand the structure and reactivity of lithiated cyclohexanone N-cyclohexylimine. The lithioimine affords complex solvent-dependent distributions of monomers, dimers, and trimers in a number of ethereal solvents. Careful selection of solvent provides exclusively monosolvated dimers. Rate studies on the C-alkylations reveal chronic mixtures of monomer- and dimer-based ...
متن کاملReductive Coupling Reactions of Nitrones and Imines, Modern Versions
INTRODUCTION Pinacol coupling was first described by Fittig in 1859, when he reported the formation of 2,3dimethyl-2,3-butanediol (1) from acetone and sodium metal. Since then, this ketyl radical anion coupling process has undergone significant advancement, including the development of asymmetric variants. 3 Alternatives to use of strong reducing metals are low valent transition metals and lant...
متن کاملReductive hydroxyalkylation/alkylation of amines with lactones/esters.
We have developed a one-pot method for the direct intermolecular reductive hydroxyalkylation or alkylation of amines using lactones or esters as the hydroxyalkylating/alkylating reagents. The method is based on the in situ amidation of lactones/esters with DIBAL-H-amine complex (for primary amines) or DIBAL-H-amine hydrochloride salt complex (for secondary amines), followed by reduction of the ...
