Effect of Doping with N, Br, and F Atoms on Electrodynamic Characteristics and Physical Properties of Isatin-β-anil

Indium(iii)-catalyzed efficient synthesis of 3-arylhydrazonoindolin-2-ones and their fluorescent metal sensing studies

“…6 They have also been used to prepare dyes and fluorescent sensors. 7,8 In particular, the installation of arylhydrazone moieties on the indolin-2-one ring has recently aroused much attention due to its potential application in photoswitches. 9 Owing to their importance, a classical condensation route was developed for the preparation of 3-arylhydrazonoindolin-2-ones via the reaction of 2-chloroindole-3-ones or isatins with arylhydrazine (Scheme 1a).…”

Visible-light-absorbing C–N cross-coupling for the synthesis of hydrazones involving C(sp2)–H/C(sp3)–H functionalization

“…40 These molecules have also been used in chemical synthesis as dyes, 41 ligands, 42 and fluorescent sensors. 43,44 The addition of hydrazone moieties on the indole ring/aryl group has attracted much attention due to its potential application in photoswitches. 45 Because of their immense relevance, numerous synthetic methods have been developed to synthesize these hydrazones.…”
