1,3‐Dipole Behavior of Phosphagermaallene Tip(<i>t</i>Bu)GeCPMes* Leading to a Phosphagermaheterocyclic Carbene

Abstract

A cyclic phosphagermacarbene is formed by a [3+2] cycloaddition between the 1,3-dipolar GeCP unit of a phosphagermaallene and an acetylene (see scheme; Tip=2,4,6-iPr3C6H3). The carbene undergoes CH insertion or is trapped by a second equivalent of acetylene derivative, and its existence and reactivity was supported by DFT calculations.
