Tandem Synthesis of 2,3,4,5-Tetrasubstituted Pyrroles from Aromatic Aldehydes Using Diethylene Glycol-bis(3-methylimidazolium) Dihydroxide as an Efficient Catalyst
A sequential process strategy was introduced for the synthesis of 2,3,4,5-tetrasubstituted pyrroles by the formation of benzoin from the corresponding aromatic aldehyde and followed by condensation reaction with 1,3-dicarbonyl compounds and ammonium acetate in the presence of diethylene glycol-bis(3-methylimidazolium) dihydroxide as catalyst in refluxing ethanol. The recycled catalyst could be ...

Although there are reports suggesting that the "sweet" taste of EG, and of products containing it, may lead to ingestion ...

This review reports some novel (or improved) synthetic methods for preparing a number of aromatic (carbocyclic and predominantly heterocyclic) organomercurials, particularly those derived from theophylline, theobromine and uracil, as well as some novel haloand cyano-demercuration reactions. We have also synthesized the first stable organic derivative of mercury(I), viz. 1,8-bis(acetoxydimercuri...
