Synthesis and Reactivity of the Amino-Functionalized β-Diketiminate Ligand Stabilized Germylene and Stannylene

Abstract

Amino-functionalized β-diketiminate stabilized chlorogermylene 1 and chlorostannylene 2 have been prepared and structurally characterized. The reactions of 1 or 2 with KO^tBu afforded the β-diketiminate stabilized tert-butoxygermylene 3 and tert-butoxystannylene 4, respectively. On the other hand, the reaction of 2 with LiN(SiMe₃)₂ led to the isolation of the bis-stannylene 5 containing a four-membered Sn₂N₂ ring. All new compounds have been characterized by multiple NMR spectroscopy and single crystal X-ray analysis.
