《Erbium anchored iminodiacetic acid (IDA) functionalized CoFe2O4 nano particles: an efficient magnetically isolable nanocomposite for the facile synthesis of 1,8-naphthyridines》 was written by Tamoradi, Taiebeh; Daraie, Mansoureh; Heravi, Majid M.; Karmakar, Bikash. Formula: C7H6O2 And the article was included in New Journal of Chemistry in 2020. The article conveys some information:
A novel functional material was developed by immobilizing an iminodiacetic acid-erbium (Er) complex onto the surface of magnetic spinel CoFe2O4 nanoparticles. The obtained nanocomposite was fully characterized using different anal. techniques such as FT-IR, XRD, SEM, BET, EDX and X-ray at. mapping anal. The catalytic activity of this novel material was investigated in the successful synthesis of 1,8-naphthyridine derivatives via a three component reaction involving 2-aminopyridine, malononitrile and various aryl aldehydes. The reactions ended up with excellent yields in short reaction times. The catalyst was reused seven times in the proposed reaction without appreciable loss of activity. In addition to this study using 3-Hydroxybenzaldehyde, there are many other studies that have used 3-Hydroxybenzaldehyde(cas: 100-83-4Formula: C7H6O2) was used in this study.
3-Hydroxybenzaldehyde(cas: 100-83-4) can be used as a reactant along with ethyl acetoacetate and thiourea in the synthesis of corresponding dihydropyrimidine-2-thione (monastrol), using Yb(OTf)3 as a catalyst by Biginelli cyclocondensation reaction.Formula: C7H6O2
