Polylithiumorganische Verbindungen. XI: 1,4-Disila[6]radialene in zwei stabilen konformationsisomeren Formen, Twist- und Sesselkonformation, die sich bei Raumtemperatur nicht ineinander umwandeln

Adalbert Maercker; Franz Brauers; Walter Brieden; Bernward Engelen

Abstract The reaction of dichlorosilanes with 3,4-dilithio-2,5-dimethyl-2,4-hexadiene yields 1,4-disila[6]radialenes in two stable conformational isomers, twist and chair, which do not interconvert at room temperature. The formation of the chair conformers is kinetically favoured. Of the two trans conformers, which are of equal thermodynamic stability, X-ray structures are presented.
