Green and Selective Synthesis ofN-Substituted Amides using Water Soluble Porphyrazinato Copper(II) Catalyst
摘要:
N, N',N '', N '''-Tetramethyl tetra-2,3-pyridinoporphyrazinato copper(II) methyl sulfate ([Cu(2,3-tmtppa)](MeSO4)(4)) efficiently catalyzed the direct conversion of nitriles to N-substituted amides. The one pot selective synthesis of the N-substituted amides from nitriles and primary amines was performed in refluxing H2O. The catalyst was recovered and reused at least four times, maintaining its efficiency.
