The article conveys some information:
Mn doped zirconia is utilized as an environment-friendly and efficient catalyst for an ultrasound mediated four-component coupling reaction, containing dimethylacetylenedicarboxylate/ethyl acetoacetate, hydrazine hydrate, malononitrile, and aromatic aldehyde RC6H4CHO [R = 2-F, 4-Br, 3-OH, 2-OCH3, 2,3-(OCH3)2, 2,5-(OCH3)2, 2,4,6-(OCH3)3]. These reactions were performed under green solvent conditions, to yield pyrano[2,3-c]pyrazole-3-carboxylate derivatives I [R1 = C(O)OCH3] and pyrano[2,3-c]pyrazole-5-carbonitrile derivatives I (R1 = CH3) with good to excellent yields (88-98%). The main benefits of this process are short reaction times, easy work-up, reusability of the catalyst and no chromatog. purifications. In the part of experimental materials, we found many familiar compounds, such as 3-Hydroxybenzaldehyde(cas: 100-83-4HPLC of Formula: 100-83-4)
3-Hydroxybenzaldehyde(cas: 100-83-4) is used as an ionophore, during the development of an highly selective and sensitive PVC membrane sensor, which can be used as a Tb3+ ion selective electrode.HPLC of Formula: 100-83-4
