  The desulfitative synthesis of aryl ketones from nitriles was also compared to the corresponding transformation starting from benzoic acids. Comparison of the energy profiles indicates that the free energy requirement for decarboxylation of 2,6-dimethoxybenzoic acid and especially benzoic acid is higher than the corresponding desulfitative process for generating the key aryl palladium intermediate. The

The acylsulphonyldiazomethanes were prepared by the action of toluene-p-sulphonyl azide and triethylamine on β-ketosulphones in 60% aqueous ethanol.

  当在干燥的甲醇中用三乙胺处理时，酰基磺酰基重氮甲烷会发生酰基裂解，从而生成α-重氮砜（约30％）。收率不佳归因于后处理过程中重氮砜的碱促进反应，因为在后处理中加入三苯基膦会生成磺酰甲醛（70-80％），这是一类以前未知的化合物，是通过水解生成首先形成磷嗪。酰基磺酰基重氮甲烷是通过甲苯-对磺酰基叠氮化物和三乙胺在60％的乙醇水溶液中对β-酮砜的作用制得的。如果重氮酮砜保留在溶液中并延长了反应时间，则可在添加三苯膦后直接分离出磺酰甲醛。
