Permethylated 3,4,7,8-tetragermacycloocta-1,5-diyne (1) and 3,4-disila-7,8-digermacycloocta-1,5-diyne (2) were prepared. The photoelectron spectra of 1 and 2 were compared with that of their tetrasila-analog 3. The first ionization potential decreases in the order of 3, 2, and 1. Charge-transfer spectra of 1-teracyanoethylene (TCNE), 2-TCNE and 3-TCNE complexes were observed. Only 1 was oligomerized
制备了全甲基化的 3,4,7,8-tetragermacycloocta-1,5-diyne (1) 和 3,4-disila-7,8-digermacycloocta-1,5-diyne (2)。将 1 和 2 的光电子光谱与其四硅类似物 3 的光电子光谱进行比较。第一电离电位按 3、2 和 1 的顺序降低。 1-teracyanoethylene (TCNE)、2-TCNE 和观察到 3-TCNE 复合物。只有 1 个在 TCNE 存在下寡聚化以产生其更高的同系物。所有 1、2 和 3 环加成到 2,3-二氯-5,6-二氰基-1,4-苯醌中,以 [2 + 6] 方式得到相应的 1:1 加合物。
