A polyimide covalent organic framework (PI-COF) with high thermal and chemical stabilities has been readily prepared from commercially available and inexpensive reagents and was employed as an effective support for heterogeneous copper. It was demonstrated that the obtained Cu@PI-COF is a highly active heterogeneous catalyst which can effectively promote the Chan-Lam coupling reaction of aryl boronic acids and amines in an open flask without the aid of any base or additive. In addition, the catalyst could be readily recovered from the reaction mixture by simple filtration and reused for at least eight cycles without any observable change in structure and catalytic activity.

Solvent-free coupling reactions of arylboronic acids with various amines were presented under ball milling conditions, achieving the aromatic amine coupling products with yields ranging from moderate to good. This type of mechano-chemistry exhibited advantages of solvent-free property, high efficiency, simple work-up procedure and eco-friendliness. This journal is the Partner Organisations 2014.
