A convenient, solvent-free Vilsmeier reagent is experimented under neat condition (both thermal and microwave conditions). An efficient method for the synthesis of various substituted 1H-pyrazole-4-carboxylic acid esters is reported.
在纯净条件下(热和微波条件下)对方便,无溶剂的Vilsmeier试剂进行了实验。报道了一种有效的合成各种取代的1 H-吡唑-4-羧酸酯的方法。
