Abstract
A porous metal-organic framework Zr6O4(OH)4(L-PdX)3 (1-x) has been constructed from Pd diphosphinite pincer complexes ([L-PdX}4 = [1,3-(OPAr2)2C6H3)PdX]4-, Ar = p-C6H4CO2, X = Cl, I). Reaction of 1-X with Phi(O2CCF3)2 generates 1-TFA, which contains more weakly coordinating CF3CO2 ligands at the Pd sites, and I2 as a soluble byproduct 1-TFA is an active and recyclable catalyst for transfer hydrogenation of benzaldehydes using formic acid as a hydrogen source. In contrast, the homogeneous analougue ^t^Bu[L-PdTFA] decomposes under the reaction conditions, resulting in poor catalytic activity.
