CARBONYL TO THIOCARBONYL CONVERSIONS USING TERTIARY AMINE-SOLUBILISED PHOSPHOROUS PENTA SULPHIDE

C SOMESWARA RAO, M P DAVE

Abstract


To continuation of our earlier work on carbonyl to thiocarbonyl conversions using triethylamine-solubilised phosphorous pentosulphide in acetonitrile at room temperature it was found that the use of triethylamine and phosphorous pentasulphide in equimolar proportions rather than in a 2:1 ratio gave very high yields of thioamides. Use of bases other than triethylamine such as diazabicyclo- [2.2.2] octane and triethylammonium acetate in this reaction is also discussed.
