Abstract
The Si-Si bond cleavage reaction of decaisopropylbicyclo[2.2.0]hexasil ane with PdCl2(PhCN)(2) gave cis- and trans-1,4-dichlorocyclohexasilan es. X-ray crystallography of these products show sterically distorted chair conformations of the Si-6 rings. The cis- and trans-cyclohexasil ane show rather different absorptions in the UV spectra. By treatment with sodium, both isomers reproduced the bicyclo[2.2.0]hexasilane quan titatively.
