Filian, Hossein; Ghorbani-Choghamarani, Arash; Tahanpesar, Elham published the artcile< 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>, HPLC of Formula: 401-78-5, the main research area is diaryl sulfide nickel guanidine nanoparticle catalyst.
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.
Journal of the Iranian Chemical Society published new progress about Adsorption. 401-78-5 belongs to class bromides-buliding-blocks, and the molecular formula is C7H4BrF3, HPLC of Formula: 401-78-5.
