Novel Stannylenes Stabilized with Diethylenetriamido and Related Amido Ligands: Synthesis, Structure, and Chemical Properties

Abstract

Abstract Complexes of divalent tin 7 – 12 with diethylenetriamines 1 – 3 and related ligands 4 – 6 were prepared from Lappert's stannylene, Sn[N(SiMe 3 ) 2 ] 2 , and the corresponding ligands. Reactivity of the stannylenes in insertion, oxidation and [1+4] cycloaddition reactions were studied. Composition and structures of the products were confirmed by elemental analyses and multinuclear ( 1 H, 13 C, 19 F, and 119 Sn) NMR spectroscopy. Crystal structures of the diethylenetriamines 1 , 2 , stannylenes 7 , 8 and the product of the reaction of stannylene 8 with an azide, which contains an eight‐membered (SnNPO) 2 ring, were determined by X‐ray diffraction study.
