of the Si–Cl bond (113 kcal/mol) and is a rare example of a transition-metal catalyzed process involving its activation. Because of the availability of both chlorosilanes and organomagnesium halide reagents, this method allows for the preparation of a wide range of alkyl and aryl silanes.
Heterogenization of Rh(II) porphyrin catalysts in a metal–organic framework is crucial for catalyst turnover in thermal olefin hydrosilylation and hydrogermylation. Unlike MOF-supported metalloradical catalysts, homogeneous analogues convert to closed shell species that obstruct catalytic turnover. Site-isolated Rh(II) metalloradicals are readily accessed via MOF synthesis with a linker containing
