Partially fluorinated heterocyclic compounds. Part 24. [1] A plausible mechanism for the formation of the fischer indole product from acetophenone 1,3,4,5,6,7,8-heptafluoro-2-naphthylhydrazone in which o-fluorine is lost

Acetophenone1,3,4,5,6,7,8-heptafluoro-2-naphthylhydrazone (1) reacts in tetralin at reflux to give 4,5,6,7,8,9-hexafluoro-2-phenylbenz[e]indole (2) as the major product, accompanied by other materials including acetophenone 3,4,5,6,7,8-hexafluoro-2-naphthylhydrazone (4) which is proposed as the true precursor to the Fisher indoleproduct (2) since it gives (2) under the same conditions. The presence
