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

Amino‐functionalized β‐diketiminate stabilized chlorogermylene 1 and chlorostannylene 2 have been prepared and structurally characterized. The reactions of 1 or 2 with KOtBu 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. Amino‐functionalized β‐diketiminate stabilized chlorogermylene and chlorostannylene featuring a RNH unit attached to the backbone carbon atom have been prepared and structurally characterized. In addition, the coordination mode of this β‐diketiminate ligand can be changed depending on the different reaction condition, and the ligand can also participate in the reaction.
