摘要
Tris(tropolonato) samarium (Ⅲ) has been prepared in high yield, by the electrochemical oxidation of samarium metal anode in acetonitrile solution of 2-hydroxy-2, 4, 6-cycloheptatrienone (trogolone, HL). The unusual divalent samarium (Ⅱ) complex was formed at the first step of electrosynthesis. The final product, Sm(C7H8O2)3, has been characterized by microanalysis and the studies of IR and 1H1 13C NMR spectra.
