A method for the catalytic C-H activation of hydrazone compounds followed by intramolecular amination is described. It requires the use of a catalytic amount of Pd(OAc)2 in the presence of Cu(OAc)2 and AgOCOCF3, which effi
Diazotisation Rearrangement of Tosylhydrazones of ortho- and meta-Substituted-benzophenones and α-Substituted-acetophenones (Synthesis of Anilides)

Ortho and meta-substituted-benzophenones (1a-g) and substituted-acetophenones (1h-i) were converted into tosylhydrazones (2a-i) by reacting with p-toluenesulphonyl-hydrazide.Conversion of 2a-i to the anilides (3a-i) was effected with the reagents H2SO4 and NaNO2, and was found to be as facile as in case of the para-substituted-benzophenone hydrozones.
