Several N,O-diacyl-N-t-butylhydroxylamines and O-acyl-N-t-butylhydroxylamines were prepared, and their thermal decompositions were studied. The thermal decompositions of N,O-diacyl-N-t-butylhydroxylamines in tetralin gave substituted N-t-butylbenzamides, carboxylic acids, 1,1′-bitetralyl, and 1,2-dihydronaphthalene as the major products, together with small amounts of carbon dioxide, t-butylamine, and benzanilides. In the thermal decompositions of O-acyl-N-t-butylhydroxylamines, the products were t-butylamine, carboxylic acids, substituted N-t-butylbenzamides, 1,1′-bitetralyl, and 1,2-dihydronaphthalene.

3,3′,4,4′-Tetrahydro-1,1′-binaphthyl can undergo dehydrogenation and cyclodehydrogenation simultaneously. Possible intermediates with various degrees of hydrogenation have been prepared and characterised. Some of these have been recognised as intermediates and thus the respective courses of the two parallel reactions have been traced.
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
