摘要

Aromatic imines react with phenylacetylene or styrene in an acetonitrile solution of iron (II1) 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 (I1) and an imine radical cation. When the reactions are carried out in the presence of stoichiometric amounts of tetrachloro- ...
