Web19 Jul 2024 · The straightforward metalation of MOF secondary building units (SBUs) with cobalt and iron salts affords highly active and reusable single-site solid catalysts for a range of organic reactions, including chemoselective borylation, silylation and amination of benzylic C–H bonds, as well as hydrogenation and hydroboration of alkenes and ketones. Websity of four-connected three-dimensional nets, that finite and infinite component units were intro-duced to describe their topologies. Finite units were introduced by Meier [1.2] and Smith [3]. The secondary building units (SBUs) of Meier, e.g., 4-, 5- or 6-rings, are invariably non-chiral. This means that only one kind of SBU rather
