ChemInform Abstract: SYNTHESIS OF SOME 1,2‐ETHANEDIAMINES

t-3-Isopropyl-r-2,c-7-diphenylhexahydro-1,4-diazepin-5-one, C20H24N2O

“…the 3-isopropyldiazepinone (II) and a 6-isopropyldiazepinone (Baliah, Lakshmanan & Pandiarajan, 1978). Schmidt reaction of the piperidone (I) has also been reported (Mohan, 1985) to yield the diazepine (II).…”

“…Recrystallization from benzene followed by ethanol afforded colourless crystals of t-3-isopropyl-r-2,c-7-diphenylhexahydro-1,4-diazepin-5-one (II); m.p. 461-462 K [literature value 461 K (Baliah, Lakshmanan & Pandiarajan, 1978)]. …”

Regeneration of Carbonyl Compounds by Deoximation of Piperidine-4-one Oximes with Quinolinium Flurochromate in Presence of Montmorillonite K10 Clay

“…163 °C and 162-163 °C). All the oximes were prepared from the respective ketones by the reported procedure [18,19].…”

Microwave Assisted Deprotection of Heterocyclic Semicarbazones by Quinolinium Flurochromate

“…163 °C and 162-163 °C) [5]. All semicarbazones were prepared from the respective ketones by the reported procedure [17,18].…”
