The reaction of tetrakis(2-tert-butyl-4,5,6-trimethylphenyl)digermene, which dissociates into germylene molecules in solution, with hexafluorobut-2-yne furnishes the corresponding germacyclopropene 3 by a [1 + 2] cycloaddition of the germylene to the CdropC triple bond. The X-ray structure analysis of 3 reveals a short C=C double bond length of 132.4(5) pm and an acute C-Ge-C bond angle of 39.93(14)degrees.
