Organically derivatised polyoxometalate (POM) clusters containing bromo or iodo groups can undergo ligand‐free, Pd‐catalysed Heck carbon–carbon coupling reactions with alkenes, with bromomagnesium phenylamide as a base (see scheme). This protocol offers a new route to organic–inorganic hybrid molecular materials in which POM clusters are covalently bonded with organic conjugated segments.
