Furnishing Amine-Functionalized Metal–Organic Frameworks with the β‑Amidoketone Group by Postsynthetic Modification

Postsynthetic
modification (PSM) of amino-functionalized metal–organic frameworks
(MOFs) to those bearing pendant β-amidoketone arms using diketene
is herein reported. Three unique MOF families demonstrate the scope
of this transformation, which both is atom-economical and yields high
conversions. In each case, the crystallinity was retained, and instances
of exceptional solid-state ordering were observed in the PSM products,
which has allowed detailed crystallographic characterization in multiple
instances.
