WebAug 15, 2011 · The synthesis and characterization of a series of bis (phosphinic)diamido yttrium alkoxide, amide, and aryloxide initiators are reported. The new complexes are characterized using multinuclear nuclear magnetic resonance (NMR) spectroscopy, elemental analysis, and, in some cases, X-ray crystallography. WebSimply heating secondary phosphine oxides and O -benzoylhydroxylamines in the presence of K 2 CO 3 gives phosphinic amides in moderate to excellent yields under air. This method provides a practical and catalyst-free method for the synthesis of various synthetically valuable phosphinic amides.
