Reactions of 5 H ,2λ 5 ‐Azaphospholes with Arylazocarbonitriles and Dialkyl Acetylenedicarboxylates Azaphospholes 1a – c react with activated arylazocarbonitriles to 1,5,2λ 5 ‐diazaphosphorines 2a – c and 3a – c . The reaction of 1a – c with diethyl or dimethyl acetylenedicarboxyiates yields 7 H ‐1,4λ 5 ‐azaphosphepines 4a – c . The structures of 2b , 3a , and 4a are established by an X‐ray diffraction analysis.
