Organometallic complexes formed between hexaalkylphosphoramides (HAPA) and transition metal salts, including rare earth metals, have been found to be effective catalysts for the oxidation of olefins to form valuable oxidation products, particularly the corresponding hydroperoxides.

Oxidation of olefins with organometallic complex catalysts

Organometallic complexes formed between hexaalkylphosphoramides (HAPA) and metal salts, including rare earth metals, have been found to be effective catalyst for the oxidation of secondary and tertiary alkylaromatics to form valuable oxidation products, particularly the corresponding hydroperoxides. Novel complexes formed between HAPA and metal salts of the lanthanide series have been found to be especially effective in the selective formation of the hydroperoxides at high conversion rates. By substantially increasing the agitation and/or aeration of the reaction medium it is possible to increase these high conversion rates still further.
