Reactions of both terminal and cyclic alkenes have been shown to occur in a stereospecifically - manner with deutrerium cyanide when a catalyst system based on Pd(DIOP)2 was used. Reactions of cyclohexene give only the products of equatorial cyanide incorporation.

study of the mechanism for oxidative heteroarylation, based on DFT calculations and experimental observations. We propose binuclear Au(II)-Au(II) complexes to be key intermediates in the mechanism for gold catalyzed oxidative heteroarylation. The reaction is thought to proceed via a gold redox cycle involving initial oxidation of Au(I) to binuclear Au(II)-Au(II) complexes by Selectfluor, followed by

base in the coupling: (1) the formation of 12, (2) the hydrolysis of Ph(Ph(3)P)(2)PdBr (14) to provide monomeric Ph(Ph(3)P)(2)PdOH (15), (3) the complexation of HOBR(2) byproducts which can compete with 10 for base, (4) accelerated coupling rates for 11, and (5) catalyst regeneration. Kinetic studies reveal that the couplings are zero-order in the borane but for 10 exhibit a first-order dependence on
