Palladium-catalyzed Heck reaction of polyoxometalate-functionalised aryl iodides and bromides with olefins.
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.
