A simple, high yielding, rapid route for the oxidative esterification of a wide range aldehydes to hexafluoroisopropyl (HFIP) esters using the oxoammonium salt 4-acetylamino-2,2,6,6-tetramethylpiperidine-1-oxoammonium tetrafluoroborate (1a) is reported. These esters can be readily transformed into a variety of other functional groups. The spent oxidant (1b) can be recovered and conveniently reoxidized to regenerate the oxoammonium salt, 1a.
本文报道了一种简单、高产、快速的方法，通过氧铵盐 4-乙酰氨基-2,2,6,6-四甲基哌啶-1-氧代铵四氟硼酸酯（1a）将多种醛氧化酯化生成全氟异丙基（HFIP）酯。这些酯可以很容易地转化为各种其他官能团。用过的氧化剂（1b）可以回收，并方便地再氧化以再生氧铵盐 1a。
