摘要: Abstract The reduction of p -anisyl(1,2,3-tri- tert -butylcycloprop-2-en-1-yl)dichlorogermane ( 1 ) with potassium in the presence an excess -butyldimethylsilane benzene under reflux gave -anisyl( -butyldimethylsilyl)(1,2,3-tri- -butylcycloprop-2-en-1-yl)germane 4 15% yield. formation indicates that -butylcycloprop-2-en-1-yl)germylene 2 ), which is first example a (cycloprop-2-en-1-yl)germylene derivative, was generated and trapped by hydrosilane. DFT calculations revealed cis -2- -anisyl-1,3,4-tri- -butyl-2-germabicyclo[1.1.0]butane-2,4-diyl structure - 5 8.0 kJ/mol more stable than . NBO analysis has 2-germabicyclo[1.1.0]butane diradical character.
