Koordinationschemie reduzierter N-Heterozyklen. Komplexe des Pyrazin-Radikalanions mit Phenylmetallkationen +MPh von Beryllium, Magnesium und Zink
Coordination chemistry of reduced N-heterocycles. Complexes of pyrazine anion radical with phenyl metal cations +MPh of beryllium, magnesium and zinc
- The diphenyls MPh2 (M = Be, Mg, Zn, Cd, Hg) have been reacted with pyrazine (Pz) in tetrahydrofuran. Only the magnesium derivative undergoes electron transfer to yield the 1:1 radical complex [Pz(MgPh)]·. However, in the presence of sodium or potassium persistent 1:2 complexes [Pz(MPh)2]+. are formed with M = Be, Mg, Zn. Use of the higher homologues CdPh2 and HgPh2 leads to reduction to the metals. The 1:2 complexes have been characterized by ESR spectroscopy; metal coupling constants of 9Be, 25Mg and 67Zn could be determined in natural isotopic abundance.
