Strong P=P π Bonds: The First Synthesis of a Stable Phosphanyl Phosphenium Ion

A 35‐fold excess of methyl triflate (2) is required to quantitively prepare 3, the first phosphanyl phosphenium ion, from diphosphene 1. Experimental data and calculations indicate that the P=P bond becomes stronger upon alkylation.
