Ni 0 -catalyzed cross-coupling of aryl methyl ethers with amines is described. The use of an N-heterocyclic carbene as a ligand and NaOt-Bu as a base promotes the amination of anisole derivatives via the cleavage of normally unreactive aryl carbon-oxygenbonds.

Arylnitriles have been found to participate in cross-coupling and amination reactions via nickel-catalyzed activation of the C-CNbond. With the development of these synthetically useful transformations, arylnitriles can now be considered along with aryl halides and sulfonates as viable substrates for these types of reactions.
Platinum/Scandium-Cocatalyzed Cascade Cyclization and Ring-Opening Reaction of Tertiary Amines with Substituted Salicylaldehydes to Synthesize 3-(Aminoalkyl)coumarins
oxidative dehydrogenation of α,β-C(sp3)−H bonds of tertiary amines in the presence of ambient oxygen followed by reactions with substituted salicylaldehydes is revealed. The in situ formed enamines reacted with various salicylaldehydes, which resulted in the development of a one-pot synthetic protocol involving aldol reaction, cyclization, and then ring-opening.
A nickel-catalyzed, efficient C-N bond reduction of aromatic and benzylic ammonium triflates has been developed using sodium isopropoxide as a reducing agent. The high efficiency, mild conditions, and nice compatibility...
