Tert-butyl hydroperoxide decomposition in the presence of initiators (tert-butyl peroxide (tBuOOtBu), azodiisobutyronitrile(AIBN)) and catalysts (Mo2B5, MoB, Mo2B, MoSi2, VB2, VSi2) was studied. Our experiments suggest that the introduction of radicals may reduce the catalytic activity. The mechanism of the initial stage of tert-butyl hydroperoxide decomposition and reaction rate equation are proposed.
