The interaction of bis(t-butylisocyano)peroxonickel(II) and bis(triphenylphosphine oxide)dibromodioxomolybdenum(VI) in the presence of cyclohexane yields 1,2-dibromocyclohexane as the main product.This result is explained by the prior epoxidation of cyclohexene, followed by its conversion into the 1,2-dibromoalkane. The epoxidation step implies peroxidation of the dioxomolybdenum by the peroxonickel species.It is shown that this occurs by a dioxygen-ligand transfer accompanied by the back transfer of two bromine atom and two triphenylphosphine oxide molecules.
