Sulfonyl chlorides as an efficient tool for the postsynthetic modification of Cr-MIL-101-SO3H and CAU-1-NH2

Abstract

Postsynthetic modification can be used to introduce sulfonamide functionalities into MOF frameworks. Using sulfonyl chlorides as reactive intermediates, Cr-MIL-SO₃H and CAU-1-NH₂ have been further modified to give hitherto unknown functionalized MOFs in which a sulfonamide group is bound to the framework either by its N or its S atom.
