5b) and 2H-germole (1-germacyclopenta-1,3-diene; 6b) as minor products. During irradiation at selected wavelengths a photoconversion of 1b into 5b and reversible interconversion of 2b and 6b have been observed and provide experimental evidence for a germylene-to-germene rearrangement. Similar experiments were carried out on deuterated analogues, and the precursor 4b-d6 produced 1b-d6, 2b-d6, 5b-d6, and
紫外光照射的基质分离的1,1-二
叠氮基-1- Gercyclocyclopent-3-ene(4b)产生1 H -Germole(1-germacyclopenta-2,4-diene; 1b)和1-germacyclopent-3-ene-1 ,1-二基(2b)作为主要产品,以及3 H -germole(1-germacyclopenta-1,4-diene; 5b)和2 H -germole(1-germacyclopenta-1,3-diene; 6b)是次要产品。在选定波长的辐射过程中,光从1b转换为5b以及可逆的2b和6b相互转换已观察到并为胚芽到
锗的重排提供了实验证据。类似的实验在
氘化的类似物进行,并且所述前体4B - d 6产生1B - d 6,2B - d 6,图5b - d 6,和图6b - d 6。基于对这些分子及其d的受限Hartree-Fock(DZ + d)计算,
