The reactions of germylenes with pentafluorophenyl- and alkylpentafluorophenyl-digermanes give the trigermanes (C6F5)3 (XP=F,Cl;=F,Ph; R=F5,Et). Their thermal decomposition involves α-elimination to give halogermanes and germylgermylenes. These last bivalent species were trapped with dimethylbutadiene to give germylgermacyclopentenes. Insertion of phylphosphinidene into the very reactive germanium—germanium
germ亚甲基与五氟苯基-和烷基五氟苯基-二茂铁的反应得到三茂铁(C 6 F 5)3(XP = F,Cl; = F,Ph; R = F 5,Et)。它们的热分解涉及α-消除,从而得到卤代金缕梅和对甲基锗烷。这些最后的二价物质被二甲基丁二烯捕获,得到了胚芽基germacyclopentenes。还观察到了叶绿体亚基插入到反应性非常强的(C 6 F 5)3 GeGe(C 6 F 5)3的锗-锗键中。

RFGeEt3 were prepared by reaction of CF3Br, CF3I or n-C4F9Br with P(NEt2)3 whereas CF2Br-CF2Br underwent by debromination and tert-C4F9I gave only FGeEt3. Interaction of CCl4, ClGeEt3 and P(NEt2)3 led to formation of CCl3GeEt3.

polynuclear species, which are sources of the mononuclear ions, The latter convert with phosphines to yield the [R3Ge-PR3]+ (4a: R = Et, 4b: R = Ph) cations. Catalytic dehydrofluorination reactions were observed for the C-F bond activation of fluoroalkanes when using germanes as hydrogen source.
