Synthesis and Characterization of a Novel Phosph(V)azane-Tin(IV) Complex
摘要:
Die reaction of bis(anilino)phosphine oxide (C6H5NH)(2)P(O)H, 1 with (Bu2SnCl2)-Sn-n in the presence of an excess of triethylamine (TEA) in dry tetrahydrofurane (THF) yields the novel N,O-bonded tin complex (Bu2Sn)-Sn-n[NPh(O)P(H)NPh(HNEt3)](2), 2. TEA is used as a base to deprotonate the phosphazane ligand and is separated as Et3NH+Cl-, whereas HTEA(+) exists in the final product 2 and act as a charge balancing and H-bond structure-directing agent. This new compound has been fully characterized by means of IR, MS, and multinuclear (H-1, P-31 and Sn-119 NMR) spectroscopy.
