A cyclic phosphagermacarbene is formed by a [3+2] cycloaddition between the 1,3‐dipolar GeCP unit of a phosphagermaallene and an acetylene (see scheme; Tip=2,4,6‐ i Pr 3 C 6 H 3 ). The carbene undergoes CH insertion or is trapped by a second equivalent of acetylene derivative, and its existence and reactivity was supported by DFT calculations.
