Harvesting the sunshine : Two new pyrrole-containing organic dyes were rationally designed and easily prepared. Thanks to the special electronic properties of pyrrole moieties and the introduction of the non-coplanar aromatic rings through a single bond (
A solvent-free manganese(II) -catalyzed Clauson-Kaas protocol for the synthesis of N-aryl pyrroles under microwave irradiation

The first manganese-catalyzed modified Clauson-Kaas reaction for N-substituted pyrrole synthesis using 2,5-dimethoxytetrahydrofuran with variously substituted aromatic amines has been developed (up to 89% yield). This interesting neat strategy is free from additives including co-catalysts, ligands, and acids. Relatively low cost, environmentally benign, and handy Mn(NO3)2·4H2O is employed as the catalyst under microwave conditions with a very short reaction time (20?min). The above qualities attest to the green nature of this reaction.

A new and efficient methodology to synthesize N-substituted pyrrole derivatives by Clauson Kaas reaction employing Oxone as catalyst was developed. The transformation was performed in acetonitrile under microwave irradiation. This procedure has several advantages such as high yield, clean product formation, and short reaction time.
