Iron-based metal–organic framework, Fe(BTC): an effective dual-functional catalyst for oxidative cyclization of bisnaphthols and tandem synthesis of quinazolin-4(3H)-ones
An iron-basedmetal–organicframework [Fe(BTC) (BTC: 1,3,5-benzenetricarboxylate)] has been shown to be an active and heterogeneous catalyst for both oxidative cyclization of methylenebisnaphthols and a modern tandem process (an in situ oxidation-aminal formation-oxidation sequence). Such a potential catalytic utility of Fe(BTC) makes it quite attractive for sustainable industrial chemistry.

Crownethers with stericrestraint imposed by a three-bladed propellersubstituent have been synthesized and the X-Ray crystal structures of one example and its NaNCS complex indicate approximately the same conformation of the propeller but quite different conformations of the ether ring in the two; n.m.r. solution spectra indicate that the flipping of the propeller and of the crown moieties are mutually
Herein, a green and efficient heterogeneous and photocatalytic system for the oxidation of bisnaphthols in acetonitrile under light-emitting diode will be presented. In this reaction, aerial oxygen and H2O2 have been used as oxidant in the presence of copper ferrite nanoparticles and N-hydroxyphthalimide as an organic co-catalyst. Copper ferrite nanoparticles were magnetically separated, the efficiency
在此,将展示一种绿色高效的多相光催化系统,用于在发光二极管下氧化乙腈中的双萘酚。在该反应中,在铁氧体铜纳米粒子和作为有机助催化剂的N-羟基邻苯二甲酰亚胺存在下,空气氧和H 2 O 2被用作氧化剂。铁氧体铜纳米粒子被磁性分离,其效率在五个周期内几乎保持不变。采用溶胶-凝胶法合成了磁性铁氧体铜纳米粒子,并通过XRD、FT-IR、SEM、TEM、VSM和DRS分析对其进行了表征。在该项目中,形成了两组非对映异构体。 图形概要 双萘酚氧化的催化体系。
