In 2019,Journal of the Iranian Chemical Society included an article by Filian, Hossein; Ghorbani-Choghamarani, Arash; Tahanpesar, Elham. HPLC of Formula: 6630-33-7. The article was titled 《Ni-guanidine@MCM-41 NPs: a new catalyst for the synthesis of 4,4′-(arylmethylene)-bis-(3-methyl-1-phenyl-1H-pyrazol-5-ols) and symmetric di-aryl sulfides》. The information in the text is summarized as follows:
In this work, the surface of mesoporous MCM-41 was modified with guanidine, and then, Nickel particles have become immobilized on its surface (Ni-guanidine@MCM-41NPs). This heterogeneous catalyst has been identified by various techniques including: low-angle X-ray diffraction, SEM, energy-dispersive X-ray spectroscopy, inductively coupled plasma, thermal gravimetric anal. and N2 adsorption-desorption measurement isotherms, and its catalytic application was studied in the synthesis of 4,4′-(arylmethylene)-bis-(3-methyl-1-phenyl-1H-pyrazol-5-ol) derivatives and sym. di-aryl sulfides. The prepared organometallic complex could be isolated, post-reaction, by simple filtration for several consecutive cycles without a notable change in its catalytic activity. After reading the article, we found that the author used o-Bromobenzaldehyde(cas: 6630-33-7HPLC of Formula: 6630-33-7)
o-Bromobenzaldehyde(cas: 6630-33-7) is used in L-threonine aldolase-catalyzed enantio/diastereoselective aldol reactions.HPLC of Formula: 6630-33-7Synthetic applications of o-Bromobenzaldehyde include: synthesis of aza-fused polycyclic quinolines through copper-catalyzed cascade reaction, preparation of 1-substituted indazoles by CuI-catalyzed coupling with N-aryl hydrazides.
