CF bond activation in polyfluorobenzothiolate compounds of Os(III). X-ray structures of [ [formula omitted]-2))(SC 6F 5) 2(PMe 2Ph) 2], [Os(SC 6F 5) 2( o-S 2C 6F 4)(PMe 2Ph)] and [Os(C 6F 5) 2( o-S 2C 6F 4)(PMe 2Ph) 2

Abstract

Thermolysis of [Os(SR) 3(PMe 2Ph) 2] (R=C 6F 5 ( 1a) or C 6HF 4-4 ( 1b)) in refluxing toluene affords [Os(SC 6F 5) 2( o-S 2C 6F 4)(PMe 2Ph)] ( 2a), [Os(SC 6HF 4) 2( o-S 2C 6HF 3)(PMe 2Ph)] ( 2b), and [Os(C 6F 5) 2( o-S 2C 6F 4)(PMe 2Ph) 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 1a, 2a and 3a have been determined. In the solid state compound 1a shows a CF→Os interaction.
