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) , RSiMe 3 , R′ t Bu. Still to be explained is the upfield shift of the 31 P‐NMR signal which can be regarded as an indication of fourfold coordination of the phosphorus.
