Reactions of titanium alcoholates Ti(OR)4 (R = n-Bu, t-Bu) with tertiary organic and organometallic hydroperoxides

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 R₃EOOH (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)₄Ti the alkoxy group is oxidized either with preservation or with breakdown of the hydrocarbon skeleton.
