, p. 1422 - 1423 (2007)
2,4-Disubstituted quinoline derivatives were obtained from N-aryl-2-propynylamines catalyzed by copper(I) and gold(I) complexes. The quinoline derivatives could also be obtained by the reaction of N-arylaldimines with terminal acetylenes via the formation of N-aryl-2-propynylamines. Copyright
Synthesis of quinolines via acceptorless dehydrogenative tandem cyclization of 2-amionbenzyl alcohol with alcohols using magnetic CuNiFeO nanocatalyst
Chaurasia, Shivkumar R.,Tiwari, Abhishek R.,Bhanage, Bhalchandra M.
, (2019)
This work reports the preparation of nano CuNiFeO and its application in the synthesis of quinolines. The prepared nanocatalyst was characterized using various characterization techniques such as XRD, FEG-SEM, EDX, HR-TEM and XPS. Nano CuNiFeO as a heterogeneous catalyst shows a very high efficiency towards double dehydrogenation tandem cyclization reaction of 2-amionbenzyl alcohol with alcohols resulting into a simple, sustainable and environment friendly synthesis of quinolines. Due to the magnetic property associated with nanocatalyst, it was easily separated from the reaction mixture using external magnet and could be reused up to five cycles. To the best of our knowledge, this is for the first time a heterogenous magnetic CuNiFeO nanocatalyst is being reported for this reaction.

2,4-Diphenylquinolines (3) were quantitatively prepared by heating of 3-aryl-4,6-diphenyl-2-oxo-1,3-diazabicyclohex-5-enes (2), which were obtained by photochemical electrocyclization of 1-aryl-4,6-diphenyl-2(1H)-pyrimidin-2-ones (1), in benzene at reflux temperature.
Dehydrogenation of N-Heterocyclic Compounds Using H2O2 and Mediated by Polar Solvents
Llopis, Natalia,Gisbert, Patricia,Baeza, Alejandro,Correa-Campillo, Jara
, p. 1205 - 1210 (2022/02/25)
The oxidative dehydrogenation of N-heterocyclic compounds by using H2O2 as oxidant in combination with polar solvents such as 1,1,1,3,3,3-hexafluoroisopropanol (HFIP) and H2O is described. Among these two solvents, the best yields for the heteroaromatic compounds were generally achieved in HFIP. However, it is remarkable, that the use of a non toxic solvent such as H2O gave such good yields. Furthermore, the procedure was implemented in larger-scale and HFIP was distilled from the reaction mixture and reused (up to 5 cycles) without a significant detriment in the reaction outcome. (Figure presented.).
