Abstract

The Cu(II) and Zn(II) chelates of 4-dimethyl-2,3,7,8-tetraethyl-15H-tripyrrin-1-one, 3-dimethyl-2,3,7,8-tetraethyl-15H-tripyrrin-1-one, andtheir sulfonate derivatives are studied. The chelates show the expected structure of an NH dideprotonated ligand chelating the metal ion. However, in the case of the Zn chelate of 14-dimethyl-2,3,7,8-tetraethyl-15H-tripyrrin-1-one the ligand is only monodeprotonated, and the lactam ring is tautomerized to a hydroximino function.
