A NEW SYNTHESIS OF 4H-THIOPYRAN-4-THIONES FROM ACETYLENIC β-DIKETONES
Marei, Mohamed Gaber
, p. 101 - 110 (2007/10/02)
2,6-Diaryl-4H-thiopyran-4-thiones have been synthesized in excellent yields by the reaction of 1-aryl-5-phenyl-4-pentyne-1,3-diones with phosphorus pentasulfide in dry pyridine at room temperature and were converted into the corresponding hydrazones and o
