Copper(II)@polyimide linked covalent organic frameworks (Cu@PI-COF) were successfully used for the efficient synthesis of 1,5-benzodiazepines via 1,2-diaminobenzene, aromatic aldehydes, and dime-done under solvent-free and microwave assisted conditions. The three-component condensation reaction provides safe operations, low pollution, quick access to products, and an easy setup due to the application of solvent-free conditions and microwave irradiation. The catalyst can be reused multiple times without any loss of activity.
Copper(II)@polyimide linked covalent organic frameworks (Cu@PI-COF) under solvent-free and microwave assisted conditions have been used in an efficient one-pot protocol for the preparation of 1,5-benzodiazepines via 1,2-diaminobenzene, aromatic aldehydes and dime -done. By applying solvent-free conditions and microwave irradiation, three-component condensa-tion provides safe operations, low pollution, quick access to products, and an easy set-up. As a result of its reusability, the catalyst can also be reutilized many runs without missing any activity.(c) 2023 The Authors. Published by Elsevier B.V. on behalf of King Saud University.
