Fig. 4 — Treatment of 1 with trimethylphosphine afforded phosphanylidene-phosphorane 2. Reactions of 1 with 2,6-dimethylphenylisonitrile and trimethylsilylnitrile yielded 1-phospha-3-azaallenes 3 and 4, respectively. 1 reacted with one and two molar equivalents of 4-tertbutylphenylazide afforded iminophosphorane 5 and bis(imino)phosphorane 6, respectively.
