Molybdenum complexes Group 8 metals

Thus, depending on the metal complex used, cyclohexene oxidation can occur via one or more of at least three major pathways, as shown in Reaction 20 path A, radical initiated decomposition of cyclohexenyl hydroperoxide path B, metal catalyzed epoxidation of the olefin and path C, metal catalyzed epoxidation of an allylic alcohol. Ugo found that path B becomes more pronounced when molybdenum complexes are used to modify the oxidation of cyclohexene in the presence of group... 

Two research groups496 497 have recently studied the autoxidation of cyclohexene at 60° to 65°C in the presence of a mixture of a low-valent Group VIII metal complex, e.g., RhCl(Ph3P)3 or (Ph3P)2Pt02, and an epoxidation catalyst (molybdenum complexes). Cyclohexen-l-ol and cyclohexene oxide are formed in roughly equimolar amounts. The results could be explained by a scheme involving two successive catalytic processes ...
