Abstract
The exceedingly different size of p orbitals is overcome in the novel doubly bonded system between phosphorus and bismuth atoms that occurs in the first stable phosphabismuthene 1. Compound 1 was obtained from the condensation reaction of Mes*PH2 with an overcrowded dibromobismuthane by using 1,8‐diazabicyclo[5.4.0]undec‐7‐ene (DBU) as a base (see scheme).
