Abstract:
A method for producing aryl alkyl hydroperoxides which comprises selectively oxidizing an aryl alkyl hydrocarbon having the formula (I): ##STR36## wherein P and Q are hydrogen or an alkyl and may be the same or different from each other; x is an integer of 1-3; and Ar is an aromatic hydrocarbon group having a valence of x, with an oxygen-containing gas in the presence of a transition metal complex containing a bridged macrocyclic polyamine compound as a ligand and having the formula (III): ##STR37## wherein B is a divalent organic group having the formula (IV): ##STR38## wherein Y.sup.1 and Y.sup.2 are independently an alkylene having 1-6 carbons in the main chain of the group of phenylene, and may carry inactive substituents thereon; R is independently hydrogen, an alkyl, an aryl, an alkyl aryl or an aryl alkyl, and the alkyl, aryl, alkyl aryl or aryl alkyl may carry inactive substituents thereon; M is a central transition metal ion having a valence of +a; X is a counter ion having a valence of -b which is stable to oxidation; a is an integer of 1-4, b is a positive integer, n is an integer of 1-4, n is equal to a/b, and m is 0 or a positive integer of 1 or more.
