Wittig reaction of a series of diazodiketones: Synthesis and structure of fluorine-containing vinyldiazoketones
Reaction of (alkyloxycarbonyl)- and (benzoyl)- methylenetriphenylphosphoranes with fluorine-containing diazodiketones leads to olefination of the perfluoroacyl carbonyl group and formation of fluorinated vinyldiazoketones. The analogous reaction with non-

Efficient synthesis of aroylperfluoroacyldiazomethanes with the use of 1,8-diazabicyclo[5.4.0]undecen-7-ene
By means of diazofunction transfer were synthesized aroylperfluoroacyldiazomethanes. The reaction was catalyzed by a weakly nucleophilic amine, 1,8-diazabicyclo[5.4.0]undecen-7-ene. The structure of fluorinatedn-2-diazo-1,3-diketones obtained was comfirme
