dcterms:description
The reaction of N,C-intramolecularly coordinated organoantimony(III) and organobismuth(III) compounds LMCl2 (M = Sb (1) or Bi (2) and L = [o-(CH=N-2,6-iPr(2)C(6)H(3))C6H4]) with phenyllithium in a 1 : 1 or 1 : 2 molar ratio gave compounds LM(Ph)Cl (M = Sb (3) or Bi (4)) and LMPh2 (M = Sb (5) or Bi (6)) in moderate to good yields. Compound 3 could also be prepared by the treatment of the lithium compound LLi with in situ prepared PhSbCl2. Oxidation of the antimony(III) compounds 1, 3 and 5 with one equivalent of SO2Cl2 proceeded smoothly with formation of organoantimony(V) compounds LSbCl4 (7), LSb(Ph)Cl-3 (8) and LSbPh2Cl2 (9) in nearly quantitative yields. Compounds 7-9 are yellowish solids that are stable for a long time even in the presence of air. In contrast, only organobismuth(III) compounds 4 and 6 could be successfully oxidized using SO2Cl2 to give compounds LBi(Ph)Cl-3 (10) and LBiPh2Cl2 (11). Compound 11 is stable, but compound 10 readily decomposed in solution and could not be isolated and stored for a longer period. All attempts to prepare compound LBiCl4 by the oxidation of 2 with SO2Cl2 failed and resulted only in a mixture of products. All studied compounds were characterized by electrospray ionization (ESI) mass spectrometry, and H-1 and C-13 NMR spectroscopy. The molecular structures of 3-7, 9 and 11 were unambiguously established using single-crystal X-ray diffraction analysis.
