Abstract tert-Butyl and cumyl hydroperoxides in the reactions with Ti (OR) 4 are reduced to alcohols with the evolution of oxygen via formation of titanium-containing peroxides and trioxides. The pathways of the reactions of Ti (OR) 4 with triphenylelement hydroperoxides R 3 EOOH (E= C, Si, Ge) depend on element E and on the structure of R; the reactions involve the rearrangement of the peroxides, and with (n-BuO) 4 Ti the alkoxy group is oxidized ...
