title: A Stable Heterocyclic Amino(phosphanylidene-σ(4)-phosphorane) Germylene.
abstract: A new stable heterocyclic germylene, in which the divalent germanium atom lies between a nitrogen atom and a phosphanylidene phosphorane group, was synthesized. Experimental and theoretical studies revealed the peculiar effect of phosphanylidene phosphorane substituent, which is a stronger π-donor towards germanium than an amino group is. Because of the weak phosphorus-germanium π-bond, this new germylene compound shows an enhanced reactivity compared to classical N-heterocyclic germylenes.
