General Description

1H-Pyrrole-2,5-dione, 1,3,4-triphenyl- is a chemical compound with the molecular formula C23H15NO2. It is an organic compound that is commonly known as triphenylpyrrole. 1H-Pyrrole-2,5-dione, 1,3,4-triphenyl- is a derivative of pyrrole, which is a five-membered aromatic ring with one nitrogen atom. The three phenyl groups attached to the pyrrole ring make 1H-Pyrrole-2,5-dione, 1,3,4-triphenyl- a highly conjugated system with potential applications in organic synthesis and material sciences. It is a yellow crystalline solid that is sparingly soluble in water but soluble in organic solvents such as dichloromethane and acetone.

An Efficient Rhodium-Catalyzed Carbonylative Annulation of Internal Alkynes and Anilines To Produce Maleimides

A selective and efficient procedure for the carbonylative synthesis of polysubstituted maleimides was developed. With rhodium as the catalyst and acetylacetone (acac) as the ligand, various desired maleimide derivatives were isolated in moderate to excellent yields with good functional group tolerance from the corresponding internal alkynes and anilines.

A Palladium-Catalyzed Cascade C-C Activation of Cyclopropenone and Carbonylative Amination: Easy Access to Highly Functionalized Maleimide Derivatives

We describe herein the first report on palladium-catalyzed C-C bond activation of cyclopropenone and concomitant carbonylative amination to produce maleimides. The interesting aspect of this reaction is that the sacrificial elimination of carbon monoxide from the substrate is efficiently recaptured by one of the intermediates in the catalytic cycle for the formation of maleimides. 18O isotopic studies confirmed that the source of carbon monoxide is from cyclopropenone.
