Abstract

We report the synthesis of a new mixed oxazoline–carbene scorpionate ligand, bis(4,4-dimethyl-2-oxazolinyl)(1-mesitylimidazolyl)phenylborate (PhB(OxMe2)2ImMes). Reactions of the protonated form PhB(OxMe2)2(ImMesH) with dialkylzinc compounds provide four-coordinate zinc alkyl complexes, and X-ray diffraction studies of the {PhB(OxMe2)2ImMes}ZnR (R = Me, Et) compounds show significant structural distortions involving the R groups shifting away from the carbene donor. The reaction of {PhB(OxMe2)2ImMes}ZnEt (3) and O2 provides an isolable mononuclear zinc alkylperoxide {PhB(OxMe2)2ImMes}ZnOOEt (4), which has been characterized by single crystal X-ray diffraction and 17O NMR spectroscopy.
