Abstract Photolysis of diazirines, 1, 3-dioxane-4, 6-dione derivatives, occurs in the presence of methanol or dimethyl sulfide as carbene traps without a formation of carbene intermediates. It was established for the first time that the thermolysis and photolysis of diazirines from the 1, 3-dioxane-4, 6-dione series led mainly to Wolff rearrangement with a subsequent formation of 5-oxo-1, 3-dioxolane-4-carboxylic acids or their derivatives.
