General description

Copper(II) nitrate trihydrate is a hydrated copper salt. It participates as catalyst in the solvent-free synthesis of 3-aminopropenones and 3-aminopropenoates.

Application

Copper(II) nitrate trihydrate may be used in the preparation of the following mononuclear copper(II) complexes (phen = 1,10-phenanthroline, dpq = dipyrido[3,2-d:2′,3′-f]quinoxaline and dppz = dipyrido[3,2-a:2′,3′-c]phenazine):
  • [Cu(dpq)(NO3)2]
  • [Cu(dpq)(NO3)(H2O)2](NO3)
  • [Cu(dpq)(NO3)2(H2O)2]·2H2O
  • [Cu(dppz)(NO3)2(H2O)]·H2O
