Oxygenation of alkylzinc complexes with pyrrolylketiminate ligand: access to alkylperoxide versus oxo-encapsulated complexes

By variation of the zinc bonded alkyl group significantly different post-oxygenation products, the novel zinc alkylperoxide and the tetranuclear zinc oxo-encapsulated cluster, were derived from the controlled oxygenation of the corresponding alkylzinc complexes with a pyrrolylketiminate ligand.
