| Abstract: | 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 C≡C 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)°. |
