OBSERVATIONS ON OLEFIN OXIDATION BY NEUTRAL AND CATIONIC PHOSPHINEIRIDIUM COMPLEXES

The ethyleneiridium oxygen complex ClIr(PPh3)2(O2)(C2H4) previously prepared by Van der Ent, decomposes in solution forming some Ph3PO and CH3CHO, in the absence of excess ethylene.It promotes the oxidation of 1-octene and styrene by O2 and factors affecting the rate and efficiency of oxidation have been examined.Tetrastyrene di-μ-chlorodiiridium is only oxidised effectively by O2 in the presence of PPh3.The 1-octene complex ClIr(PPh3)2(C8H16) reacts very rapidly with oxygen at low temperatures but 2-octanone is not found in the decomposition products.The cationic complex (C2H4)Ir+(PPh3)2 promotes the oxidation of 1-octene and styrene but low yields of products are formed, including phenyloxirane and benzaldehyde.Complexes of 5-phenyldibenzophosphole were examined.They are not effective in promoting oxidation and display a strong tendency to form stable five-coordinate complexes and a greater propensity for cis-biphosphine coordination.
