Abstract
We have prepared four potentially lipophilic N-substituted hydroxypyridinones containing unsaturated hydrocarbon groups. The propyl vinyl ether derivative (3) has been characterized by an X-ray diffraction study. Complexes of the type cis-MoO2L2, where L represents the hydroxypyridinonato ligands, have also been prepared. The pyridinone ligands are bound to molybdenum in a cis bidentate fashion via the deprotonated hydroxy groups and the ketone moieties. Initial investigations into the hydroboration of the alkene groups in the pyridinone ligands and corresponding metal complexes is presented. Crystals of (3) are monoclinic, with a 10.466(1), b 13.388(1), c 15.386(2) Å, β 102.343(8)˚, Z 8, space group P21/n.Keywords: Molybdenum; pyridinones; hydroboration; boronic acids.
