Research paper thumbnail of Mechanistic studies of nickel catalysis in the cross coupling of aryl halides with alkylmetals. Role of arylalkylnickel(II) species as intermediates

Journal of the American Chemical Society, Dec 1, 1975

The infrared active stretchlng mode v(C%) is a sensitive probe of acetylene cmrdlnation in Pd(ll), Pt(ll), Pd(O), and Pt(0) complexes.65 We have found no infrared evidence for metal-acetylene *-interactions either in the solid state or in solution in a variety of organic solvents for any of the complexes P d C l d P h m R) 2 (R = CF3, Ph, Et. CPr, t-Bu). While we cannot completely rule out this possibility, our results can be adequately erplalned without invoking such Interactions. (65) S. E. Jacobson. A.

Journal of Organometallic Chemistry, 1975

Abstract The possibility of electron transfer being the initiation step in free radical pathways ... more Abstract The possibility of electron transfer being the initiation step in free radical pathways in oxidative addition is probed by exposing nickel(0) and platinum(0) species to a variety of electron acceptors; one-electron transformations are found to be facile in these systems.
