eng	Preparation of Stibinidenes and Bismuthinidenes and Their Use as Ligands for TM	TM complexes of sub(low)-valent p-block element compounds have attracted considerable attention not only because of their unique structures, but also in the regard to their synthetic potential in organometallic chemistry. Our group has recently succeeded in the synthesis and structural characterization of the first monomeric stibinidene and bismuthinidene stabilized by an effective coordination of the N,C,N-pincer type ligand. The main drawback of this investigation was both relatively complicated synthesis of the N,C,N-ligand precursor and low yields of these low-valent products observed after reduction of trivalent precursors. For these reasons, we modified the ligand backbone and we obtain new monomeric stibinidenes and bismuthinidenes. These monovalent RE(I) (E = Sb, Bi) species contain two electron lone pairs available for TM coordination. In this contribution, the reactivity of monovalent stibinidenes and bismuthinidenes with selected TM complexes will be presented.
