摘　　要：在微波辐射、碘化钾及聚乙二醇-600的催化下,合成了一系列不同取代的芳硫丙酸,并进一步在微波辐射及多聚磷酸的作用下合成了相应的硫色满酮.产物结构由红外光谱、核磁共振氢谱、质谱及元素分析等确证.该方法的优点是产率较高、反应速度快,而且操作也大为简化.Under microwave irradiation, a series of β-arylthioethers of propionic acid were prepared by catalysis of KI/PEG-600. The corresponding thiochromanones were synthesized from β-arylthioethers of propionic acid under microwave irradiation in the presence of polyphosphoric acid. Their structures were confirmed by IR, ^1H NMR, MS spectra and elemental analysis. The advantages of the procedure were short reaction time, high yield and simple work up.
