Ionic liquids have been emerging as a versatile class of green solvents with many projected advantages compared with conventional media. They have been described as "designer solvents" whose properties such as solubility, density, refractive index, and viscosity can be adjusted to suit requirements simply by making changes to the structure of either anion or cation or both. In organic synthesis, ionic liquids have been extensively used for the variety of synthetic transformations. Recently, plethoras of nitrogen heterocycles have been synthesized using variety of structurally diverse ionic liquids. In the present review, I would account the synthesis of various kinds of nitrogen heterocycles using variety of ionic liquids from the beginning to the recent reports.

A rhodiumA C H T U N G T R E N N U N G (III)-catalyzed amidation between benzoic acids and isocyanates via direct functionalization of an ortho C À H bond followed by intramolecular cyclization is described. This cascade cyclization affords N-substituted phthalimides in one step in 26-91% yields. The reaction is highly atom-economical, since no theoretical waste except for water is generated in the reaction.

2008 Carboxylic amides Q 0490 Ionic Liquid [bmim][BF4] Acts as Solvent and Promoter for Synthesis of Halo-Containing N-Arylphthalimides.-Phthalic anhydride reacts with aromatic amines in ionic liquid to give the pharmacologically interesting phthalimides. The yield of the second run is higher than in the first one and does not decrease in the third and fourth run. The purity of the products is the same in all cases. -(CHEN*, D. C.; YE, H.
