room-temperature Pd-catalyzed acetoxylation of pyrroles with phenyliodonium acetate is described. The acetoxylation was found to proceed via the initial formation of pyrrolyl(phenyl)iodonium acetates, which were converted to acetoxypyrroles in the presence of Pd(OAc)2. The acetoxylation could also be carried out as a one-pot sequential procedure without the isolation of the intermediate iodonium salts.
描述了吡咯与乙酸苯基碘铵的温和,室温下钯催化的乙氧基化。发现乙酰氧基化是通过最初形成吡咯基(苯基)碘乙酸盐进行的,在Pd(OAc)2存在下将其转化为乙酰氧基吡咯。乙酰氧基化反应也可以按照一锅法的顺序进行,而无需分离中间的碘鎓盐。
