Sub-nanometric Cu clusters formed by endogenous reduction of Cu salts and Cu nanoparticles are active and selective catalysts for C-N, C-C, C-O, C-S, and C-P bond-forming reactions. Sub-nanometric Cu clusters have also been generated within a polymeric film and stored with full stability for months. In this way, they are ready to be used on demand and maintain high activity (TONs up to 10(4)) and selectivity
通过内源性还原铜盐和铜纳米粒子形成的亚纳米级铜簇是 CN、CC、CO、CS 和 CP 键形成反应的活性和选择性催化剂。亚纳米级的 Cu 簇也已在聚合物薄膜中生成,并且可以完全稳定地储存数月。通过这种方式,它们可以按需使用并保持高活性(TON 高达 10(4))和上述反应的选择性。介绍了形成亚纳米簇的潜在机制及其电子性质。
