Solid State Oxidation of Alcohols Using l-Butyl-4-aza-l-azoniabicyclo[2.2.2]octane Chlorochromate

摘要

Oxidation of organic compounds is one of the most important reactions in modern organic synthesis.For this purpose,some new oxidizing reagents have been prepared.Unfortunately most of them suffer at least from one of the following disadvantages:1) high cost of preparations,2) long reaction time,3) hygroscopisity,4) high acidity,5) instability,6) no selectivity,7) photosensitivity,8) dangerous procedures for their preparation and 9) tedious work-up procedures.The quest for effective oxidant that use inexpensive oxidant,which works under solvent-free or non-aqueous and neutral conditions for converting alcohols to carbonyl compounds,remain an important challenge.
