A Stable Heterocyclic Amino(phosphanylidene s(4) phosphorane) Germylene.
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 p donor towards germanium than an amino group is. Because of the weak phosphorus germanium p bond, this new germylene compound shows an enhanced reactivity compared to classical N heterocyclic germylenes.
