The reaction of α-benzenesulfonylphenylacetic acid with some alkyl halides, using as base NaH in DMSO, leads to decarboxylative protonation to give benzylphenylsulfone. Decarboxylative alkylation occurs only when CO2 is expelled by flushing with nitrogen. The mechanism of the decarboxylative protonation is investigated.
α-苯磺酰基苯乙酸与一些卤代烷反应,在 DMSO 中使用 NaH 作为碱,导致脱羧质子化,得到苄基苯砜。脱羧烷基化仅在通过用氮气冲洗排出 CO2 时发生。研究了脱羧质子化的机理。
