Reactions of substituted 4-diazotetrahydrofurane-3-ones with various acids (pKa 2 + cation was confirmed by density functional theory (DFT) calculations at the PBE0/6-31+G(d) functional due to good agreement between calculated and experimental data on the acid stability of diazoketones in different solvents.

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

The biradicals generated in the type II photoreaction of 1-aryl-2,4-dimethylpentane-1,3-diones (1) were trapped by oxygen to form biradical-oxygen complexes.In acetonitrile, pentane, or benzene, 5-aryl-2,2,4-trimethylfuran-3(2H)-ones (2), 6-aryl-6-hydroxy-3,3,5-trimethyl-1,2-dioxan-4-ones (3), and arene carboxylic acids (4) were produced via biradical-oxygen complexes, whereas in alcoholic solvents, 4-aryl-4-hydroxy-3,5,5-trimethyl-4,5-dihydrofuran-2(3H)-ones (5) were produced in addition to (2), (3), and (4).

Photolysis of 2,4-dimethyl-1-phenylpentane-1,3-dione (1) in the presence of oxygen gave 2,2,4-trimethyl-5-phenylfuran-3(2H)-one (2) and 6-hydroxy-3,3,5-trimethyl-6-phenyl-1,2-dioxan-4-one (3) via the interaction of the type II biradical with oxygen.
