azoles with 2,2′,4′-trichloroacetophenone (TCA) under solvent-free conditions allowed to obtain the corresponding 1-(2′,4′-dichlorophenacyl) azoles with satisfactory to good selectivities and yields. TGA and DSC measurements were achieved for the synthesized compounds and showed a close relationship between the thermal behavior and the reaction temperature under microwave heating. Non-purely thermal microwave
在无溶剂条件下用2,2',4'-三氯苯乙酮(TCA)微波诱导几种唑的N-烷基化反应,可以得到相应的1-(2',4'-dichlorophenacyl)唑,具有令人满意的选择性和良好的收率。对合成的化合物进行了TGA和DSC测量,结果表明,在微波加热下,热行为与反应温度之间存在密切关系。在所选条件下,在吡唑和1H-吲唑的烷基化过程中证实了非纯热微波效应。
