Abstract
Samarium (III) 1,1,1,6,6,6-hexafluoro-3,4-di(2-thiophenemethanone) hexanedionate-2,5 was obtained from thenoyltrifluoroacetone by electrochemical synthesis. Mass spectrometry and IR spectroscopy data showed that electrolysis resulted in the formation of both the tetraketonate ligand and the quasi-aromatic metallocycle, the main structural element of the chelate. The peripheral groups (trifluoromethyl and thenoyl) of the tetraketonate ligand were not transformed by the electric current. The resulting samarium chelate compound is a promising precursor for the synthesis of orange-emitting light-emitting diodes and active laser media.
