Intramolecular bissilylation under high pressure yields the ethene derivative 1 , whose structure is not twisted about the CC bond. Its UV spectra and crystal structure suggests that the weak absorption at 361 nm is attributable to the fourfold Si substitution and not, as previously suggested for tetrakis(organosilyl)ethenes, from twisting.
