The sterically congested disilanes tBu2XSiSiXMes2 [X = H (1), X = Cl (2)] have been prepared. An X-ray structure analysis of 1 reveals a preference for the anti-conformation in the solid state. Similar results have been obtained by empirical force field calculations and DNMR spectroscopy. Reaction of 2 with an electron rich olefin leads to a chlorine bridged disilanyl radical whereas treatment with alkali metals yields the corresponding disilenyl radical anion, tBu2Si=SiMes2˙̄.
