Some new germanium analogues of 1,3-cyclohexadiene, 3,4,5,6-tetraphenyl-, 3,6-diphenyl-, and 3,4,5,6-tetramethyl-1,2-digermacyclohexa-3,5-diene and 3,4,5,6-tetraphenyl-1-germa-2-silacyclohexa-3,5-diene, were prepared and fully characterized by spectroscopic methods. On photolysis, the 1,2-digermacyclohexa-3,5-diene underwent extrusion of dialkylgermylene (R2Ge:) to give the corresponding germacyclopentadiene
1,3-环己二烯,3,4,5,6-四苯基-,3,6
-二苯基-和3,4,5,6-四甲基-1,2-二甲基环己-3,5-的一些新的
锗类似物制备了二烯和3,4,5,6-四苯基-1-
锗-2-
硅环六-6-3,5-二烯,并通过光谱法对其进行了全面表征。在光解中,将1,2-二硬脂基环己-3,5-二烯进行二烷基亚
锗烯(R 2 Ge :)的挤出,以得到相应的生殖
环戊二烯。在辐射下,1-germa-2-silacyclohexa-3,5-diene通过挤出R 2 Ge:优先产生了silacyclopentadiene 。讨论了这些光解的机理。
