The intensiostatic sacrificial anode technique proved to be efficient for the silylation of 2-bromo- and 2,5-dibromofurans with trimethylchlorosilane and diorganodichlorosilanes with high selectivity and versatility not accessible by pure chemical routes. Furylsilanes, bromofurylsilanes, bis(furyl)silanes, bis(bromofuryl)silanes, furylchlorosilanes, bis(silyl and chlorosilyl)furans, poly[(silanylene)furylene] oligomers and [1(4)]dimethylsila-2,5-furanocalixarene were obtained in good to high yields.
