Abstract

Molecular oxygen was used as the primary oxidant in transition metal substituted heteropolyanion, SiM(H₂O)W₁₁O₃₉ ^q-(M = Mn³⁺, Cu²⁺, Co²⁺, Fe³⁺), catalysed oxidative transformations of olefins in the presence of reducing agents. Product selectivity depended on the reductant used; thus in the presence of sodium dithionite allylic oxidation products were formed, collodial platinum and hydrogen catalysed epoxidation, and the use of sodium borohydride yielded saturated alcohols with both Markownikoff and anti-Markownikoff orientations.
