3-dimethylbut-1-ene and 3,3-dimethylcyclopropene. These experimental data and the total vibrational analysis of I supplement the information obtained in the series of investigations of tert-butyl, trimethylsilyl, trimethylgermyl, trimethylstannyl, and trimethylplumbyl derivatives of 3,3-dimethylcyclopropene.
进行1,2-二叔丁基-3,3-二甲基环丙烯(I)的合成,并测量其IR和拉曼光谱。在HF / 6-31G *和CCSD / cc-pVDZ水平下可获得I的最佳几何形状。从头算出的光谱用于实验光谱数据的分配。将获得的结果与3,3-二甲基丁-1-烯和3,3-二甲基环丙烯的相应数据进行比较。这些实验数据和I的总振动分析补充了在3,3-二甲基环丙烯的叔丁基,三甲基甲硅烷基,三甲基锗烷基,三甲基锡烷基和三甲基铅基衍生物系列研究中获得的信息。
