We report the synthesis of a new mixed oxazoline-carbene scorpionate ligand, bis(4,4-dimethyl-2-oxazolinyl)(1- mesitylimidazolyl) phenylborate (PhB(Ox(Me2))(2)Im(Mes)). Reactions of the protonated form PhB(Ox(Me2))(2)(Im(Mes)H) with dialkylzinc compounds provide four-coordinate zinc alkyl complexes, and X-ray diffraction studies of the {PhB(Ox(Me2))(2)Im(Mes)} ZnR (R = Me, Et) compounds show significant structural distortions involving the R groups shifting away from the carbene donor. The reaction of {PhB(OxMe2)(2)Im(Mes)} ZnEt (3) and O-2 provides an isolable mononuclear zinc alkylperoxide {PhB(Ox(Me2))(2)Im(Mes)} ZnOOEt (4), which has been characterized by single crystal X-ray diffraction and O-17 NMR spectroscopy.
