Procedure

1.98 millimoles styrene were added to a solution of 5.34 millimoles active oxygen in the form of the complex of hexamethyl phosphotriamide of oxodiperoxomolybdenum (MoO5 -HMPT) in 50 ml 1,2-dichloroethane, the mixture was then maintained at 40° C. for 4.5 hours whereupon the reaction products were anlysed by gas chromatography. 0.35 millimoles benzaldehyde and 0.08 millimoles alpha-tolualdehyde were obtained. The degree of conversion with respect to the olefin consumed was 43%. The results are given in table 1.
