摘要：

Significant downfield shifts in the NMR spectrum are displayed by the central Si atoms in compounds 1 relative to those of disilenes not having four silyl substituents. The extraordinary color change of 1c on dissolving in hexane (yellow → deep red) is particularly impressive and indicates a conformational change caused by reduction in steric strain.
