Synthesis of Bis‐ and Tris(3‐H‐1, 3‐azaphospholo)benzenes. Issue 1 (6th November 2013) - Marchenko, Anatoliy
ABSTRACT The previously developed intramolecular cyclocondensation of C‐phosphanyl(N‐aryl)formamidines into 3‐H‐1, 3‐benzazaphospholes has been successfully extended to 1, 3‐diaminobenzene and 1, 3, 5‐triaminobenzene. Its condensation presents the way to tricyclic and tetracyclic azaphospholes. Their structures were confirmed by spectroscopic methods and key tricyclic and tetracyclic compounds were further characterized by single crystal X‐ray diffraction.
