Reactions of Titanium Alcoholates Ti(OR)_4 (R =n-Bu,t-Bu)with Tertiary Organic and Organometallic Hydroperoxides

摘要

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_3EOOH (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.
