The cyclic stannylenes I which are accessible by transamination from [Sn(NSiMe 3 ) 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.
