Herein, we developed an operational simple, practical, and selective Ni-catalyzed synthesis of secondary amides. Application of renewable alcohols, earth-abundant and nonprecious nickel catalyst facilitates the transformations, releasing water as byproduct. The catalytic system is tolerant to a variety of functional groups including nitrile, allylic ether, and alkene and could be extended to the synthesis

intermediate. This intermediate is converted to the final products via reductiveamination with an appropriately functionalized benzylamine, followed by hydrogenolysis and lactam formation. Because derivatization occurs late in the synthesis, the approach is general, requiring only modification of the purification procedures for each newderivative. To aid in the purification of the bicyclic malonamides, we report
Reductions of carboxylic acid derivatives by silanes in the presence of rhodium complexes were studied. Carboxylic esters were reduced to alcohols by diphenylsilane catalyzed by [RhCl(cod)]2/4PPh3 ...

A series of rutheniumcomplexes can perform the acceptorlessdehydrogenation of diols as well as the reaction of amines and alcohols to form ester, lactam, and amide products. The ligand criteria necessary for high catalytic activity are identified to guide future catalyst development for amide formation from amines and alcohols. These complexes can be employed in a dehydrogenative Paal–Knorr pyrrole
Fulleroisoquinolinones have been synthesized by palladium-catalyzed annulation of N-alkyl benzamides with C(60). A device incorporating fulleroisoquinolinones and the conjugated polymer P3HT exhibited power conversion efficiency up to 2.3% under AM 1.5G irradiation.
