Isolable aryl‐substituted silyl radicals (tBu2MeSi)2(Ar)Si. (Ar=C6H5, 4‐tBuC6H4, 4‐PhC6H4, 3,5‐tBu2C6H3) were synthesized by the reaction of the corresponding iodosilane with an equimolar amount of potassium graphite (KC8) in tetrahydrofuran (THF). The crystal structure of 3,5‐tBu2C6H3 derivative, which was determined by X‐ray crystallography, showed a planar geometry around the Si atom for the radical...
