CO2 LASER-INDUCED INTERACTION BETWEEN SULFUR HEXAFLUORIDE AND CARBON DISULFIDE

Interaction between carbon disulfide and sulfur hexafluoride is excited by cw CO2 laser radiation and has been investigated for different ratiosover a pressure range from 3.1 to 34.6 kPa.The reaction yields sulfur tetrafluoride, sulfur, carbon, thiocarbonyl fluoride, tetrafluoromethane and hexafluoroethane, the ratio of these latter products is dependent on the partial pressure of sulfur hexafluoride in the initial CS2-SF6 mixture.Interaction is considered to include both the SF6-sensitized decomposition of carbon disulfide and reaction between sulfur hexafluoride and carbon disulfide.

Unusual reaction of Grignard reagents with bis(trifluoromethyl)disulfide

Simultaneous scission of the C-S and S-S bonds of bis(trifluoromethyl)disulfide occurs on treatment with Grignard reagents at -78 deg C and gives rise to unsymmetrical disulfides and sulfides as well as alkyl sulfides.Under similar experimental conditions, alkyl disulfides are recovered unreacted.Probable mechanisms of the cleavage reactions are presented.

TRANSFORMATION OF ORGANOPHOSPHORUS S-TRIFLUOROMETHYLTHIOATES RR'P(O)SCF3 INTO FLUORIDES RR'P(O)F. STEREOCHEMICAL ASPECTS OF THIOCARBONYL FLUORIDE EXTRUSION

The stereochemical course of the thermal or by nucleophiles catalyzed extrusion reaction of thiocarbonyl fluoride from two diastereomeric (6) and optically active (10) organophosphorus S-trifluoromethylthioates has been investigated.To explain the observed retention of configuration at phosphorus in fluoridates 7 formed in the thermal reactions, a four center transition state for such reactions has been proposed.The lack of the stereoselectivity in the catalyzed reactions of 6, and the observed racemization of the final product 11 are briefly discussed.
