Abstract

An efficient method for the formation of SiCl₃ radicals by the reaction of abundant and cheaper chlorosilanes with DyI₂ has been established, not only demonstrating new distinctive reactivities of solvated DyI₂ but also suggesting that the presence of lanthanide ions can improve the selectivity of some silyl radical-catalyzed reactions.
