On the basis of deuterium labeling experiments and an equal 1,2-/1,4-product distribution, the reductive elimination of the product has been established to be the enantioselective step in the nickel-catalyzed hydrocyanation of 1,3-cyclohexadiene. Thi

The steric course of the first step of Pd(0)-catalyzed allylic substitution with stabilized C-nucleophiles can be completely reversed by a suitably positioned coordinating Ph2P group, resulting in an overall inversion (1 → 4 → 5), as opposed to t

Nickel complexes having a bulky tri(sec-alkyl)phosphine ligand catalyze hydroheteroarylation of alkynes at 35 degrees C. Selective activation of an Ar-H bond over an Ar-CN bond of N-protected 3-cyanoindoles is achieved by a proper choice of ligand an

Deuterium gas exchanges slowly with liquid methanol over Raney nickel catalyst at 35 deg . The reaction is zero order with respect to deuterium pressure and has a low activation energy. The influences of catalyst weight, catalyst treatment, and of th
