Lead alkoxide complexes Pb(OEt)4,Pb(OBu)4,Pb(OCH2CH2OCH3)4,Pb(OEt)2(acac)2,Pb(OBu)2(acac)2 and Pb(OCH2CH2OCH3)2(acac)2 were directly synthesized by means of electrochemical dissolution of lead in a cell without any diaphragm. The products were characterized by FT-IR,Raman spectra and NMR.The experimental results show that selecting R4NBr as the conductive additive could improve product yields and prevent the lead anode from passivation.The data also show that a direct electrochemical preparation of lead complexes Pb(OCH2CH2OCH3)4,Pb(OEt)2(acac)2,Pb(OBu)2(acac)2 and Pb(OCH2CH2OCH3)2(acac)2 exhibits a high current efficiency and a high electrolysis yield.
