 Title    Triazaphosphinine — Reaktionen, Zwitterionen, P—B-Austausch Triazaphosphinines — Reactions, Zwitter Ions, P — B-Exchange  
 Abstract    -triazaphosphinine (2) reacts with SbF, in the molar ratio 3:1 to give the mixed halogenated triazaphosphinine (3). New addition compounds 5 and 6 can be formed in the reaction of the zwitter ion 4 and amines or in the reaction of 2.2-difluoro-triazaphosphinine (1) with KCN. Phosphorus-boron-exchange is observed in the reactions of 4 or 2 with BF : , • OEt 2 . The new C—B —N-heterocycles 8 and 9 are obtained. The gas-phase structure of 1 has been deter-mined by electron diffraction. The scattering intensities are compatible with a planar ring confor-mation with C, v symmetry and with equivalent NC bond lengths (PN = 1.579(10) Ä, NC = 1.299(7) Ä, NPN = 109.2(7)°, PNC -118.1(9)°, CNC -119.6(7)° and NCN = 127.5(12)°).
