Palladium-catalyzed addition of silyl-substituted chloroalkynes to terminal alkynes

Better together: A novel hybrid N-heterocyclic carbene (NHC) palladium complex, integrating a totally inorganic and polyanionic decatungstate unit, has been synthesized following a convergent strategy. The interplay of the Pd binding domains with the inorganic scaffold is instrumental in accessing multi-turnover catalysis in C-C crosscoupling and aromatic dehalogenation reactions under MW-assisted protocols (see scheme).
