title: Solvent-Induced Assembly of Sliver Coordination Polymers (CPs) as Cooperative Catalysts for Synthesizing of Cyclopentenone[b]pyrroles Frameworks.
abstract: A series of solvent-induced Ag-based coordination polymers (CPs) (1-3), which were synthesized by regulating the size, shape, and polarity of solvent molecules (EtOH, iPrOH, 1,4-dioxane) as structure-directing agents, has been used as heterogeneous catalysts to explore how the metal-metal bonds could serve as cooperative catalysis for tandem acylation-Nazarov cyclization reaction to prepare cyclopentenone[b]pyrroles frameworks. Structural conversions from a three-dimensional (3D) framework of 1 to the structure of 2 with Ag-Ag-Ag bonds and to the two-dimensional (2D) framework of 3 with Ag-Ag bonds, arising from the different sizes, shapes, and polarities of the solvent molecules, were observed. Futhermore, the effective cooperative catalysis for tandem acylation-Nazarov cyclization reaction has been evidenced by the significantly transformed connection modes of Ag-Ag interactions in 1-3. As a result, the unique structural characteristics of 2, especially containing the Ag-Ag-Ag bonds, endow 2 with intact multinuclear reaction pathways and well-defined multinuclear platforms that can execute tandem acylation-Nazarov cyclization reaction through the cooperative effect of Ag-Ag-Ag interactions during the catalytic process.
