On the Nature of Initiating Species in Radical Addition Reactions Promoted by R2Zn/O2 and Related RZn(L)/O2 Systems

摘要

For decades reactions of zinc alkyls with O2 has have been commonly considered as difficult to control due to their the radical-chain character, which significantly has prevented the more rapid design and implementation of O2-based reaction systems. Our recent systematic investigation have dispelled the decades of uncertainties surrounding reactions of zinc alkyls with O2. We have provided efficient methods for the selective oxygenation of zinc alkyls toward desired alkylperoxides, alkoxides or oxides as well as a plausible hypothesis concerning the mechanism of O2 activation by organometallic compounds has certainly been advanced.
