摘要：

The rate-determining stage in the Bamford-Stevens reaction is shown to be a unimolecular elimination from the anion of the sulphonylhydrazone. This gives, apparently in all cases, a secondary aliphatic diazo-compound, which then undergoes thermal decomposition. Such diazo-compounds may decompose in solvents rich in available protons, such as were originally used by Bamford and Stevens, mainly via the diazonium cation, and the reaction then degenerates into a variant of the normal deamination reaction. Acetamide is a convenient solvent for minimizing this effect, and gives higher yields of hydrocarbon products.
