The data suggests that Na2 eosin Y-derived photoinduced states act as a HAT catalyst for
the synthesis of 3, 4-dihydropyrimidin-2-(1 H)-ones/thiones in ethanol at room temperature …

Preparative nanoZnO and ZnO have been found as reusable catalysts for either
condensation or dissociation of urea to ammonia and controllable selectivity in the Biginelli …

We report here an efficient and green method for Biginelli condensation reaction of
aldehydes, β-ketoesters and urea or thiourea catalyzed by Brønsted acidic ionic liquid …

In this paper, we wish to report the synthesis and characterization of sulfonated-phenylacetic
acid coated on Fe 3 O 4 nanoparticles by a simple method. This catalyst was effectively …

Based on the Biginelli reaction of β-ketoesters, arylaldehydes, and urea/thiourea, we
created a green radical synthesis procedure for 3, 4-dihydropyrimidin-2-(1H)-ones/thiones …

The catalytic application of a novel ionic liquid and sulfonic acid based bifunctional periodic
mesoporous organosilica (BPMO–IL–SO3H) in the one‐pot Biginelli reaction was …
