Aldehydes are transformed into stable gem-difluoro compounds. Upon standard SRN1 reaction conditions, they generate anion radicals that undergo a very fast fluoride elimination to produce methylene quinones which are alkylated by a nucleophile. This process gives rise to facile access to new fluorinated species having any side chain. It is the first reported example of gem-difluoro compounds reacting by the SRN1 mechanism.
醛转化为稳定的偕二
氟化合物。在标准 SRN1 反应条件下,它们产生阴离子自由基,该阴离子自由基经过非常快速的
氟化物消除,产生亚甲基醌,并被亲核试剂烷基化。该过程可以方便地获得具有任何侧链的新
氟化物质。这是第一个报道的偕二
氟化合物通过 SRN1 机制反应的例子。
