Tin Analogues of "Arduengo Carbenes": Synthesis of 1,3,2λ2-Diazastannoles and Transfer of Sn Atoms between a 1,3,2λ2-Diazastannole and a Diazadiene

Tin Analogues of "Arduengo Carbenes": Synthesis of 1,3,2λ2-Diazastannoles and Transfer of Sn Atoms between a 1,3,2λ2-Diazastannole and a Diazadiene

The cyclic stannylenes I which are accessible by transamination from [Sn(NSiMe3)2] and α‐amino aldimines undergo easy cheletropic decomposition and may formally transfer a “naked” tin atom to a diazadiene. Computational studies suggest an electronic polarization in the form of the chelated atom cano...

Description
Summary:The cyclic stannylenes I which are accessible by transamination from [Sn(NSiMe3)2] and α‐amino aldimines undergo easy cheletropic decomposition and may formally transfer a “naked” tin atom to a diazadiene. Computational studies suggest an electronic polarization in the form of the chelated atom canonical structure I′ as the reason for this behavior.
