eng	Reactions of N,C,N-chelated pnictinidenes with Rh(I) and Ir(I) complexes: Coordination vs. Transmetalation	The reaction of N,C,N-chelated pnictinidenes ArE(I) [ where Ar = C6H3-2,6-(CH = Nt-Bu) 2, E As (1) and Sb (2)] with dimeric complexes [(COD) M(mu-Cl)] 2 (where COD = 1,5-cyclooctadiene, M = Rh or Ir) gave pnictinidene complexes [ArEM(Cl) (COD)] [where E = As, M = Ir (3) and E = Sb, M = Ir (4), Rh (6)] that were characterized by the help of H-1 and C-13 NMR spectroscopy and in the case of 3 and 6 also with the single-crystal X-ray diffraction analysis. However, the complex [ArAsRh(Cl) (COD)] (5) could not be isolated and exists only in an equilibrium with starting compounds in solution. The treatment of other Rh(I) precursors, such as [(COT)(2)Rh (mu-Cl)(2) (COT = cyclooctene), with 1 or 2 led to the rhodium (III) pincer complex ArRhCl2 (7) as a results of a transmetalation. Complex 7 was completely characterized including the single-crystal X-ray diffraction analysis. Finally, the reactivity toward the rhodium(I) carbonyl complex [(CO)(2)Rh (mu-Cl)](2) was studied. In the case of the stibinidene 1, an insoluble material was obtained, while the arsinidine derivative cis-[ArAsRh(Cl) (CO)(2)] (8) could be isolated and characterized by NMR and IR spectroscopy.
