The reactions of diarylgermanes with alkali metals in HMPA/THF or THF were found to give the corresponding diarylgermylenedialkali metals in high yields. Diphenylgermylenedipotassium reacted with aryl halides or carbonyl compounds to give reduction products predominantly. With alkyl halides, diphenylgermylenedipotassium gave mainly substitution products.

burnt in an aneroid combustion bomb and the enthalpy of sublimation measured by a combination of d.s.c. and effusion: Δ f H m o (C 6 H 5 ) 2 Ge(CH 2 ) 4 , cr} = (34.3 ± 10.0) kJ · mol −1 ; Δ f H m o (C 6 H 5 ) 2 Ge(CH 2 ) 4 , g} = (138.9 ± 10.5) kJ · mol −1 . The gas-phase molar enthalpy of formation has been used to investigate strain in the ringsystem.
摘要 化合物 (C 6 H 5 ) 2 Ge(CH 2 ) 4 已在无液燃烧弹中燃烧,并通过 dsc 和 effusion 组合测量升华焓:Δ f H mo (C 6 H 5 ) 2 Ge(CH 2 ) 4 , cr} = (34.3 ± 10.0) kJ·mol -1 ;Δ f H mo (C 6 H 5 ) 2 Ge(CH 2 ) 4 , g} = (138.9 ± 10.5) kJ·mol -1 。气相摩尔生成焓已用于研究环系统中的应变。
