Structure of the 1:1 Adduct of Aminoiminophosphane and tert-Butyl Azide

A tetraazaphospholine (3), rather than a bridged triazaphosphetine (2), is formed on addition of (1) to tert‐butyl azide; this was shown by X‐ray structure analysis of (3), RSiMe3, R′tBu. Still to be explained is the upfield shift of the 31P‐NMR signal which can be regarded as an indication of fou...

Zusammenfassung:A tetraazaphospholine (3), rather than a bridged triazaphosphetine (2), is formed on addition of (1) to tert‐butyl azide; this was shown by X‐ray structure analysis of (3), RSiMe3, R′tBu. Still to be explained is the upfield shift of the 31P‐NMR signal which can be regarded as an indication of fourfold coordination of the phosphorus.
