Structural and conformational analysis of 1-monofluorosilacyclobutane and 1-monochlorosilacyclobutane. A gas-phase electron diffraction adn ab initio investigation

摘要

The structures of numerous 1,1-disubstituted silacyclobutanes have been investigated thoroughly, but none of the monosubstituted silacyclobutanes have investigated thoroughly, but none of the mono-substituted representatives have been studied as yet. In the present work the geometric structures and conformational equilibria substituted representatives have been studied as yet. In the present work the geometric structures and conformational equilibria of 1-monofluorosilacyclobutane (MFSCB) and 1-monochlorosilacylobutane (MCSCB) have been investigated by means of gas-phase electrondiffraction and ab initio calculations.
