产品描述

General description

Bobbitt′s salt (oxoammonium salt) is a commonly used oxidizing agent in organic synthesis for the preparation of useful chemical intermediates. This reagent is highly stable to both air and moisture.[1][3]

巴比氏盐(氧铵盐)是有机合成中常用的氧化剂,用于制备有用的化学中间体。 该试剂对空气和湿气都高度稳定。

Application

Bobbitt′s salt (4-NHAc-TEMPOBF4 −) can be used as a reagent in:       
•  Oxidation of alcohols to their concomitant aldehyde, ketone or carboxylic acid.[1][3]      
•  Conversion of aldehydes to hexafluoroisopropyl (HFIP) esters via oxidative esterification.[3],·        
•  Deprotection of allyl ethers to corresponding aldehydes.[5]
•  Preparation of α,β-unsaturated ketones by dehydrogenation of perfluoroalkyl ketones.[4]
巴氏盐(4-NHAc-TEMPO + BF4-)可在以下场合用作试剂:

•醇氧化为其伴随的醛,酮或羧酸。•通过氧化酯化将醛转化为六氟异丙基(HFIP)酯。 •将烯丙基醚脱保护为相应的醛。 •通过全氟烷基酮的脱氢制备α,β-不饱和酮。
