Pd/C-catalyzed facile synthesis of primary aromatic amides by aminocarbonylation of aryl iodides using ammonia surrogates

摘要: Use of Pd/C as an efficient, phosphine free, heterogeneous and recyclable catalyst for one pot carbonylative synthesis primary aromatic amides has been demonstrated. The developed protocol is simple to perform employs ammonium carbamate in situ solid ammonia source which feasible more convenient than direct use gas. applicability the was studied various aryl iodide substrates it found that provides good excellent yields desired amides. easily separable shows significant recyclability up four consecutive cycles without loss catalytic activity.
