A Coordination Polymer of Vaska's Complex as a Heterogeneous Catalyst for the Reductive Formation of Enamines from Amides
In this work, a low-valent metal-organic material is synthesized using a tetratopic phosphine linker and Vaska's complex. This crystalline, IrI-containing material behaves similarly to Vaska's complex, binding dioxygen reversibly and can also be used as a recyclable, heterogeneous catalyst for the reductive formation of enamines from amides.
Low-valent metal–organic frameworks (LVMOFs) and related materials have gained interest due to their potential applications in heterogeneous catalysis. However, of the few LVMOFs that have been reported, none have shown catalytic activity. Herein, a low-valent metal-organic material constructed from phosphine linkers and IrI nodes is reported. This material is effectively a crystalline, insoluble analogue of Vaska's complex. As such, the material reversibly binds O2 and catalyzes the reductive formation of enamines from amides.Zum Volltext
