The sensitized photoexcitation of 2-diazocyclopentane-1,3-diones in the presence of THF leads to the insertion of the terminal N-atom of the diazo group into the α-С–Н bond of THF, producing the associated N-alkylhydrazones in yields of up to 63

The energies and lifetimes of the excited states (S1, S2, S5, T1) of a diazotetrahydrofuranone were determined using experimental and computational methods. It was shown that direction of the diazoketone photochemical transformations without eliminat

The interaction of 5,5-dialkyl(diaryl)-substituted 4-diazo-3(2H)furanones with Bronsted acids (TFA, TsOH, etc.) causes elimination of nitrogen accompanied by 1,2-nucleophilic rearrangement, giving rise to exclusive formation of 4,5-dialkyl(diaryl)-su

Benzophenone-sensitized reactions of 4-diazotetrahydrofuran-3(2H)-ones with H-donors such as tetrahydrofuran, 1,4-dioxane, cyclohexane and diethyl ether, occur without elimination of nitrogen and give rise to the corresponding N-substituted hydrazone

The formation of C–H insertion products in the course of direct photolysis of α,α-diphenylsubstituted diazo ketones of the tetrahydrofuran series was rationalized by secondary photochemical processes which give rise to benzophenone acting as a se
