Although metal-organic frameworks (MOFs) can be used in many reactions, their applications in acid involved reactions are limited due to their instability in acid environment. As a stable MOF, the Ir(III)-porphyrin metal-organic framework of the formula [(Hf6(μ3-O)8(OH)2(H2O)10)2(Ir(TCPP)Cl)3]?solvents (Ir-PMOF-1(Hf)) can sustain its structure upon treatments in different pH (0–11) aqueous solutions. In this work, Ir-PMOF-1(Hf) has been examined in the O?H insertion reaction of carboxylic acids with diazo compounds. Catalytic results show that as low as 0.042 mol % of Ir-PMOF-1(Hf) can promote the acid O?H insertion with the maximum turn over number (TON) of 1381, and furthermore, it can be recycled and reused for 10 runs, suggesting that Ir-PMOF-1(Hf) is efficient for this acid involved reaction. Ir-PMOF-1(Hf) can also be miniaturized to nano scale (diameter range of 400–500 nm), and a large improvement with regards to TON (8400) can be observed in its catalysis.
