Unimolecular decomposition pathways are challenging to address in transition-metal catalysis and have previously not been suppressed via incorporation into a solid support. Two robust metal-organic frameworks (IRMOF-10 and bio-MOF-100) are used for the architectural stabilization of a structurally well-defined gold(III) catalyst. The inherent rigidity of these materials is utilized to preclude a unimolecular decomposition pathway—reductive elimination. Through this architectural stabilization strategy, decomposition of the incorporated gold(III) catalyst in the metal-organic frameworks is not observed; in contrast, the homogeneous analog is prone to decomposition in solution. Stabilization of the catalyst in these metal-organic frameworks precludes leaching and enables recyclability, which is crucial for productive heterogeneous catalysis.

单分子分解途径在过渡金属催化中难以解决，并且以前没有通过掺入固体载体中而被抑制。两个坚固的金属有机骨架（IRMOF-10和bio-MOF-100）用于结构明确的金（III）催化剂的结构稳定化。这些材料的固有刚度可用于排除单分子分解途径-还原消除。通过这种体系结构稳定化策略，未观察到金属有机骨架中结合的金（III）催化剂的分解。相反，均质类似物易于在溶液中分解。在这些金属-有机骨架中稳定催化剂可防止浸出并实现可回收性，这对于生产性多相催化至关重要。
