The first 1,2‐azaphosphindoles 14a,b , 15a,b were obtained in a straightforward manner upon heating diphenylzirconocene in the presence of a cyanophosphane, which afforded azazirconacyclopentenes 11a,b which can be reacted with various dichlorophosphanes. The use of the tetrachlorodiphosphane Cl 2 P(CH 2 ) 2 PCl 2 instead of a dichlorophosphane allowed the preparation of the bis(1,2‐azaphosphindoles) 19 , 19 ′. The monosulfur adduct of the azaphosphindole 14a , i.e. 16a , was characterized by X‐ray structure analysis. Alkylation of 14a or 16a with methyltrifluoromethane sulfonate occurred selectively on the intracyclic phosphorus atom or on the sulfur atom, giving the salts 20 or 21 , respectively.
