Rohit, Kizhakkekuttu Radhakrishnan published the artcileA solvent-free manganese(II) -catalyzed Clauson-Kaas protocol for the synthesis of N-aryl pyrroles under microwave irradiation, Name: 4-(1H-Pyrrol-1-yl)phenol, the publication is Journal of Heterocyclic Chemistry (2022), 59(1), 194-200, database is CAplus.
The first manganese-catalyzed modified Clauson-Kaas reaction for N-substituted pyrroles I (R = Ph, 2-bromo-4-methylphenyl, 1,3-benzothiazol-2-yl, etc.) synthesis using 2,5-dimethoxytetrahydrofuran with variously substituted aromatic amines RNH2 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.
