| Abstract: | Thermolysis of [Os(SR)(3)(PMe2Ph)(2)] (R = C6F5 (1a) or C6HF4-4 (1b)) in refluxing toluene affords [Os(SC6F5)(2)(o-S2C6F4)(PMe2Ph)] (2a), [Os(SC6HF4)(2)(o-S2C6HF3)(PMe2Ph)] (2b), and [Os(C6F5)(2)(o-S2C6F4)(PMe2Ph)(2)] (3a) through processes involving C-F and C-S bond cleavage as well as rearrangement of C-S bonds. The single-crystal diffraction structures of la, 2a and 3a have been determined. In the solid state compound 1a shows a C-F --> Os interaction. (C) 2000 Elsevier Science S.A. All rights reserved. |
