Dimethoxytetramethyldisilane: overcoming the limitations of palladium-catalyzed C-H silacyclization of 2-iodobiphenyls

Herein, a readily accessible silicon reagent (dimethoxytetramethyldisilane) has been developed for time-controlled palladium-catalyzed C−H silacyclization of 2-iodobiphenyls. This protocol enables divergent synthesis of dibenzooxadisilepines and dibenzosiloles in moderate to excellent...
