摘要：

The thermal stability of diazodiketones strongly depends on the twisting of the molecular framework caused by steric interaction of substituents at the carbonyl groups. On going from planar cyclic 2-diazo-4,4-dimethyltetralin-1,3-dione to sterically congested mesitoylpivaloyldiazomethane the rate of decomposition increases 100 times. On the other hand, bulky substituents also decrease the reactivity of 2-ketoketenes formed in the Wolff rearrangement of these diazocarbonyl compounds.
