✦ Synopsis

The oxidation reaction of alkanes by t-butylhydroperoxide TBHP in the presence of titanium alkoxides produced the corresponding alcohols and ketones. The feature of this reaction was different from titanosilicate, although the tetra-alkoxide structure of titanium alkoxides is similar to titanosilicate. Other titanium complexes with titanyl or peroxo-titanium groups were not effective. This oxidation reaction proceeded in radical mechanism. t-Butoxyl radical formed from TBHP and Ž . titanium alkoxide started the radical reaction. The evolution of oxygen the decomopsition of peroxide and the abstraction of hydrogen from alkane to form alkyl radical occurred competitively.
