摘要：
Nitrogen-rich of a melamine-based mesoporous covalent organic frameworks (COFs) materials were synthesized and used as a carrier to support a Pd(OAc)(2). The Pd@OC-MA revealed an efficient catalytic activity and selectivity for Suzuki-Miyaura coupling reactions in an environmentally friendly water medium at room temperature. Specifically, it had moderate to excellent conversion for inactive chlorinated aromatic hydrocarbons. The catalyst was synthesized simply, had high stability and good selectivity, and was easy to recycle. Excellent catalytic activity of the Pd@OC-MA was also observed after five consecutive cycles.
