SYNTHESIS AND FLUORESCENCE OF 4-METHYLSULFANYL-6-PYRIDYL-2H-PYRAN-2-ONES IN SOLID STATE

摘要

Various 4-methylsulfanyl-6-pyridyl-2H-pyran-2-one derivatives were synthesized by the reaction of ketene dithioacetals with active methyl or methylene compounds in the presence of powdered sodium hydroxide in dimethyl sulfoxide (DMSO). Among these 2-pyrone derivatives,3-aryl-4-methylsulfanyl-6-pyrid-2-yl-2H-pyran-2-ones show strong fluorescence in the solid state.
