Abstract

Aryl halosilanes and their hypervalent derivatives are versatile reagents for carbon–carbon [1–2] and carbon–heteroatom [3] bond formation in modern organic synthesis. Although they have been prepared by arylation of halosilanes with aryl magnesium or aryl lithium reagents,[4] and by Pd-catalyzed cross-coupling of halogenated disilanes with aryl electrophiles,[5] direct silylation of arenes through CÀH bond activation would provide a ...
