PRODUCTION OF FLUORANILINE DERIVATIVES. |
| abstract |
(A) Fluoraniline derivs. of formula (I) are new (B) intermediates of formulae (II) are new when A=CN or lower alkoxycarbonyl provided that when X=NH, A=CN. Prepn. comprises reductive cyclisation of cpd of formula (II) where A=CN, COOH or lower alkoxycarbonyl. Reaction is pref (1) in presence of a catalyst (esp. PtO2, Pd-on-C or Raney Nt) under H2 atmos. or (2) by chemical redn. pref. with a metal (esp. iron or zinc powder) and an acid (esp. HCl, H2SO4 or acetic acid). |
