Abstract:
The heavier cyclobutadiene analogue 2,4-digerma-1,3-diphosphacyclobutadiene ([L12Ge2P2], 4; L1 = CH{(CMe)(2,6-iPr2C6H3N)}2), featuring a planar Ge2P2 four-membered ring, has been synthesized via the elimination of carbon monoxide from the corresponding phosphaketenyl germylene [L1GePCO] (2) under UV irradiation.
