The Preparation, Lithium Aluminum Hydride Reduction, and Electronic Spectra of Halogen-substituted 3,4-Bis(diphenylmethylene)-cyclobutenes and -cyclobutanes
hydride afforded halogenfree cyclobutane. The mechanism of the reduction is discussed. The cyclobutenes showed their K-bands in a wavelength region ca. 100 nm shorter than in the cases of the corresponding cyclobutanes. Furthermore, the K-band of the cyclobutenes is comparable to that of 1-phenylbuta-1,3-diene. On the basis of the electronic spectral data, a puckeredstructure was postulated for the cyclobutenes
制备了标题化合物,并研究了它们的理化性质。环丁烯用氢化铝锂还原得到无卤环丁烷。讨论了减少的机制。环丁烯在大约波长范围内显示出它们的 K 带。比相应的环丁烷短 100 nm。此外,环丁烯的 K 带与 1-苯基丁-1,3-二烯的 K 带相当。根据电子光谱数据,假设环丁烯具有褶皱结构。
