| Abstract | Crystal and molecular structure analysis of the electron rich title compound exhibits an undistorted, yet sterically shielded tetra(primary alkyl)-substituted double bond system with alternating anti-periplanar CH :SiMe 3 substituents. The diastereotopic methylene protons have been located and their position correlated to the 'HNMRdataand to theESRhyper f inecoupl ingcons tan t s of the corresponding radical cation. In contrast to the highly inert all-carbon derivative, tetraneopentylethene, the more electron-rich and more flexible organosilicon title compound reacts with bromine. Close to orthogonal arrangement between the C—C(H:)—Si planes and the ethene plane ensures effective, fourfold a/jr-hyperconjugation. |
