“…Acidic ion exchange resins, such as Amberlite IR 120H, were also found to be excellent catalysts for the condensation reaction of aryl aldehydes and hydroxylamines (Scheme 18 ) [ 89 ]. The solvent-free reactions provided high yields in short reaction times.…”

“…These reactions resulted in almost complete conversion. In particular, microwave irradiation proved to be highly effective in promoting the condensation reactions [26][27][28][29][30][31]. Microwave was applied in nitrile formation with dehydrating agents such as peroxymonosulfate / alumina, sodium hydrogen sulphate / SiO2, or HY-Zeolite, anhydrous Na2SO4 and anhydrous NaHCO3 [32].…”

“…TfOH showed reactivity comparable to perchloric acid, and the reaction was complete in 9 h (entry 10). Amberlyst-15 is an excellent heterogeneous catalyst, and we demonstrated for the first time that it gave nitrile 4a in good yield (entry 11). Amberlyst-15 can be recovered by filtration and reused 20 times for the same reaction (Figure S1).…”
