3-Acyl-1,3-diaryltriazenes as neutral and selective acylating agents
摘要:
New 3-acyl-1,3-diaryltriazenes have been prepared and their reactions with amino compounds have been studied. Reactions proceed rapidly under mild conditions to give the corresponding N-acyl products: Reagents enable chemoselective acylation of aliphatic primary and secondary amines in the presence of other acylable functional groups.

Biologically active 4-nitro-substituted 1,3-diaryltriazene, a chemical analogue of 1,3-bis(4'-amidinophenyl)-triazene-berenil®, belongs to the novel, chemically modified class of potent antitumor agents. Its structural characterization by X-ray analysis and 1H NMR spectroscopy is performed to determine molecular overall conformation in view of its possible interaction to DNA.

Synthesis and Characterization of New Triazenide Salts
Stable triethylammonium triazenide salts were obtained on treatment of the appropriate triazenes with triethylamine. Those salts are described and fully characterized for the first time and are used for the preparation of alkoxycarbonylvinyltriethylammonium triazenides, which are prone to transesterification.
