Pd-catalyzed C-H activation/C-N bond formation: A new route to 1-aryl-1H-benzotriazoles

A method for the C-H activation of aryl triazene compounds followed by intramolecular amination is described. It involves the use of a catalytic amount of Pd(OAc)2 that efficiently effects the cyclization to provide 1-aryl-1H-benzotriazoles at moderate temperature.

Nitrosation with Sodium Hexanitrocobaltate(III)

Na3Co(NO2)6 has been investigated as a new reagent for the nitrosation of various substrates containing an amino functionality. Reactions took place in an aqueous solution of the reagent. The pH of the reaction mixture remained in the range 4.3-5. Thus, hydrazides were transformed to the corresponding acyl azides, and the reactions with arenesulfonyl hydrazines afforded arenesulfonyl azides. Treatment of aromatic amines with Na3Co(NO2)6 gave 1,3-diaryltriazenes in excellent yields; coupling of the initially formed diazo compound to the electron rich aromatic ring was also observed. Nitrosation of aliphatic amines was not possible due to complex formation with the reagent.
