摘要：

1,3-Disilacyclopent-4-ene has been synthesized and its far-infrared, mid-infrared, and Raman spectra have been analyzed. From the far-infrared data of the molecule in the vapor phase, which shows a series of 10 bands between 48 and 85 cm-1, the ring-puckering potential energy surface was determined to be V (cm-1) = 1.48 x 10(5)x4 + 0.30 x 10(4)x2, where x is the ring-puckering coordinate in angstroms. This shows the molecule to be planar but to be not nearly as rigid as silacyclopent-2-ene. Other features in the infrared, Raman, and NMR spectra confirm that the interactions between the silicon atoms and the carbon-carbon double bond, while present, are reduced relative to silacyclopent-2-ene.
