HIGH-YIELD ELECTROSYNTHESIS OF FURYLCHLOROSILANES, SILYL AND SILANYLENE FURANS

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