| Überführung von Triazaphospholen in Diazaphosphole durch Acetylenaddition/Nitrileliminierung [1] Conversion of Triazaphospholes into Diazaphospholes by Acetylene Addition/Nitrile Elimination [1]  | | | | Abstract
| Acetylene di-and (less easily) monocarboxylic esters replace nitriles from the 4,5-position of 1,2,4,3-triazaphosphole rings to give carboxyl derivatives of 1,2,3-diaza-phospholes, presumably by a cycloaddition/cycloreversion mechanism. In cases with a mobile N-substituent alternatively the loss of N2 seemed feasible, but was normally not observed. | | | |

| 4.5 -Dicyano-1.3.2A 3 -diazaphospholat - ein anionisches, als Monomer stabiles 1.3.2-Diazaphosphol [1] 4,5-Dicyano-1,3,2 A 3 -diazaphospholate -an Anionic 1,3,2-Diazaphosphole, Stable as a Monomer [1] | | | | Abstract
| Diamino-maleodinitrile and P(NMe2)3 condense at room temperature to the dimethyl -ammonium salt of the dicyano-1,3,2-diazaphosphole. Other products may result under different conditions. Mel methylates the ambivalent diazaphosphole anion at nitrogen. | | | |
