are conveniently synthesized. Similar experiments at controlled temperature (25 ± 1° C) resulted in comparable yields, showing the promotional role of ultrasound irradiation in the progress of the reaction. GRAPHICAL ABSTRACT
摘要 几种芳基甲基酮与胺和元素硫的非热、无溶剂缩合可在短时间内使用超声波辐射有效地进行。因此,可以方便地合成各种硫代乙酰胺。在受控温度 (25 ± 1° C) 下进行的类似实验产生了可比的产率,显示了超声辐射在反应进程中的促进作用。图形概要
Infrared spectra of several thiopiperidides and thiomorpholides
A new decarboxylative strategy has been developed for the synthesis of thioamides via a three-component reaction involving arylacetic or cinnamic acids, amines and elemental sulfur powder, without the need of a transition metal and an external oxidant.
