The validity of Scheme I is supported by the fact that benzene which would arise from the decomposition of the hydrido-olefin intermediate 2 (step e) is formed, with a few exceptions, only in the cases where not isopropylbut n-propylbenzene is formed preferentially. The electronic effects of the ligands attached to nickel channel the reaction via one of the pathways in preference to the other. An increase in the electron density on nickel owing to ...
