Abstract
  • A substitutionally labile tungsten(II) reagent, W(CO)3(acac)2 (acac = acetylacetonate) has been synthesized and isolated. Initial reactivity investigations include replacement of one CO ligand with two-electron donors, such as phosphines, or replacement of two equivalents of CO with conventional four-electron donor ligands, such as alkynes and nitriles. Aldehydes, imines, and ketones surprisingly bind to tungsten as four-electron donors relying on lone-pair donation from the heteroatom to satisfy the eighteen electron requirement... Formally, the original sidebound nitrile ligand undergoes three ligand based manipulations while being reduced to a sidebound iminium ligand.
