Oxidative Povarov reaction of N-benzylanilines was realized under catalytic radical cation salt induced conditions. The mechanism studies revealed that a radical intermediate was involved in this catalytic oxidation. This method provides a new way to synthesize 2,4-diarylquinoline derivatives.

A cascade process involving the Povarov reaction and hydrogen transfer catalyzed with p-sulfonic acid calix[4]arene was disclosed and afforded the synthesis of 2,4-disubstituted quinolines in good yields under appropriate conditions in a single pot proces
Synthesis of photochromic spirooxazines from 1-amino-2-naphthols

, p. 9669 - 9678 (2007/10/03)
A synthetic access to photochromic spirooxazines is developed through the condensation of methylene-substituted azaheterocycles on 1-amino-2- naphthols in presence of an oxidizing agent. Compared to usual preparation of this kind of compounds (via 1-nitroso-2-naphthols), yields are generally good and approaches to further spiroheterocyclic oxazines are possible.
Annulation Reactions with Iron(III) Chloride: Oxidation of Imines

Aromatic imines react with phenylacetylene or styrene in an acetonitrile solution of iron(III) chloride to give quinolines 3 or their tetrahydro derivatives 11 together with variable amounts of products 4 arising from the reduction of the imines.The initial step appears to be a one-electron oxidation to generate iron(II) and an imine radical cation.When the reactions are carried out in the presence of stoichiometric amounts of tetrachloro-p-benzoquinone (chloranil), only quinolines 3 are obtained.
THE REACTION OF IMIDOYL RADICALS WITH MULTIPLE CARBON-CARBON BONDS
Leardini, Rino,Nanni, Daniele,Tundo, Antonio,Zanardi, Giuseppe
, p. 637 - 642 (2007/10/02)
A general view on the reaction between imidoyl radicals and carbon-carbon double or triple bonds is given; the synthesis of substituted quinolines starting from imines and alkenes is described, pointing out the differences with respect to the analogous reaction performed with alkynes.
