“…72 A few ketones (camphor, cyclopentanone, and cyclohexanone) can behave similarly, but this is not general. More frequently, ketones and nitriles condense to form β-amido ketone products in modest yield (equation 32).…”

“…Ein wichtiges Verfahren, das weithin für die Herstellung von Polyester, Polyamid, Polyether und anderen Kunststoffen eingesetzt wird, ist die Polykondensation . Sie arbeitet mit einem schrittweisen Wachstumsmechanismus und liefert als Zwischenprodukt Polymere mit verschiedenen Längen und einer breiten Molekulargewichtsverteilung, die weiter miteinander reagieren und letztlich eine unkontrollierte Struktur ergeben.…”

“…5 Generally symmetrical alkylidene bisamides are synthesized by the direct reaction of aldehydes with the corresponding amides under suitable catalytic condition. In this topic, let us examine the various conditions of the catalysts such as sulfuric acid 6 , sulfonic acid 7 , triflic acid 8 , p-toluene sulfonic acid 9 , SiO 2 -MgCl 2 10 , hydrochloric acid 11 , CC-or DCMT activatd DMSO 12 , phosphotungstic acid 13 , boric acid 14 , silica coated magnetic NiFe 2 O 4 nanoparticle supported polyphosphoric acid 15 and p-toluenesulfonic acid. 16 Our studies towards the development of more efficient methods accompanied with higher yields for the synthesis of N,N'-Alkylidene bisamides in the presence of nano-TiCl 4 .SiO 2 .…”
