A small series of new 3,5‐dimethyl‐4‐(arylsulfanyl)pyrazoles have been synthesized in good to excellent yields by a grinding‐induced, sequential one‐pot three‐component reaction, of an equimolar mixture of 3‐chloro‐2,4‐pentanedione, differently substituted thiophenols, and hydrazine hydrate in the presence of piperidine under solvent‐free conditions.
通过研磨诱导的,顺序的一锅三组分反应,等摩尔的3-氯-2-基混合物的合成,已经合成了少量新的3,5-二甲基-4-(芳基硫烷基)吡唑,收率良好。 ,在无溶剂条件下,在哌啶存在下,4-戊二酮,不同取代的硫酚和水合肼。
