A convenient access to some new and known bis(pyrazolyl)methanes synthesis has been successfully achieved
via an alternative Knoevenagel/Michael reaction of aromatic aldehydes and pyrazole-5-one in the presence of Mohr’s salt
as a green catalyst. This novel procedure has some advantages such as high efficiency, simplicity, high rate and environmental
Keywords: Green synthesis, Knoevenagel condensation, Michael addition, aqueous media, bis(pyrazolyl)methane, Mohr’s salt.
