The Reaction of White Phosphorus with Lithium (Trimethylsilyl)diazomethanide: Direct Access to a New, Aromatic 1,2,3,4‐Diazadiphosphole Ring

Abstract

A formal [2 + 3]cycloaddition between [PP] and a diazomethyl anion affords the anionic, aromatic five-membered ring [RCP2N2]− (R = Me3Si) [Eq. (a); counterion Li+]. This reaction is a rare example of the use of P4 in organic synthesis.
