Abstract

1,n-(alkane-1,n-diyl)-bis-3-phenylhydrazono(hydroxyimino)-indolin-2-
ones 12-17 have been synthesized from isatin. Thus, the condensation of isatin 1
with dibromoalcanes under liquid-solid phase transfer catalysis (PTC)
conditions affords 1,n-bis-(isatin)alkanes which reacted with phenylhydrazine
and hydroxylamine hydrochloride in refluxing ethanol.
The structures of all compounds synthesized have been characterized by using
1H NMR and 13C NMR spectroscopy.
