Reaction of cyclotrisilane 1 with lithium yields, depending on the reaction conditions, either the trisilane 2 lithiated at the terminal positions or the vicinal dilithiodisilane 3 . These silanes are the first examples of this class of compounds and the first to be characterized by X‐ray structure analysis. Ar = 2‐(Me 2 NCH 2 )C 6 H 4 .
