Gp. Kantin et Va. Nikolaev, Efficient synthesis of aroylperfluoroacyldiazomethanes with the use of 1,8-diazabicyclo[5.4.0]undecen-7-ene, RUSS J ORG, 36(4), 2000, pp. 486-488
By means of diazofunction transfer were synthesized aroylperfluoroacyldiazo
methanes. The reaction was catalyzed by a weakly nucleophilic amine, 1,8-di
azabicyclo[5.4.0]undecen-7-ene. The structure of fluorinatedn-2-diaazo-1,3-
diketones obtained was comfirmed by IR, UV, H-1, C-13, F-19 NMR spectra and
also by preparation of crystalline triphenylphospbazines.
