Hydroperoxidations of Alkenes using Cobalt Picolinate Catalysts

Abstract

Hydroperoxides were synthesized in one step from various alkenes using Co(pic) 2 as the catalyst with molecular oxygen and tetramethyldisiloxane (TMDSO). The hydration product could be obtained using a modified catalyst, Co(3-mepic) 2 , with molecular oxygen and phenylsilane. Formation of hydroperoxides occurred through a rapid Co−O bond metathesis of a peroxycobalt compound with isopropanol.
