Postsynthetic Metalation of Robust Hydrogen-Bonded Organic Framework for Heterogeneous Catalysis



Bin Han, Hailong Wang, Chiming Wang, Hui Wu, Wei Zhou, Banglin Chen, Jianzhuang Jiang


Hydrogen-bonded organic framework (HOF)-based catalysts still remain unreported thus far due to their relatively weak stability. In the present work, a robust porous HOF (HOF-19) with a Brunauer-Emmett-Teller surface area of 685 m2 g^-1^ was reticulated from a cage-like building block, amino-substituted bis(tetraoxacalix[2]arene[2]triazine), depending on the hydrogen bonding with the help of π-π interactions. The post-synthetic metalation of HOF-19 with palladium acetate afforded a palladium(II)-containing heterogeneous catalyst with porous hydrogen-bonded structure retained, which exhibits excellent catalytic performance for Suzuki-Miyaura coupling reaction with the high isolation yeilds (9698%), prominent stability recrystallization, the catalytic activity of deactivated species can be recovered from the isolation yield 46% to 92% for 4-bromobenzonitrile conversion at the same conditions, revealing the great application potentials of HOF-based catalysts.
