A low pressure microflow system was developed for palladium-catalyzed multiphase carbonylation reactions in an ionic liquid. The microflow system resulted in superior selectivity and higher yields in carbonylative Sonogashira coupling and amidation reactions of aryl iodides compared to the conventional batch system.
[reaction: see text] The aerobic oxidation of 4-monosubstituted 1,2-diphenylpyrazolidine-3,5-diones 1 was carried out in the presence of a catalytic amount of manganese(III) acetate to quantitatively give the corresponding 4-hydroperoxypyrazolidinediones 2. A similar autoxidation of the 5-monosubstituted barbituric acids 5 and 3-butyl-4-hydroxy-2-quinolinone 7 also gave the corresponding hydroperoxides 5 and 8, respectively, in moderate to excellent yields.
