Multistep CO2 Reduction Catalyzed by [Ru(bpy)2(qu)(CO)]2+ (bpy = 2,2'-Bipyridine, qu = Quinoline). Double Methylation of the Carbonyl Moiety Resulting from Reductive Disproportionation of CO2
摘要:
The title complexes catalyze the reductive disproportionation of CO2 forming CO and CO32- in the electrochemical CO2 reduction in CH3CN with LiBF4. The same reduction in the presence of Me(4)NBF(4) instead of LiBF4 produces CH3C(O)CH3 and CH3C(O)CH2COO- in addition to HCOO- and CO in CH3CN/DMSO (1:1, v/v). In this reaction Me(4)N(+) functions as the methylation agent of the carbonyl moiety resulting from the reductive disproportionation of CO2. The produced CH3C(O)CH3 undergoes the abstraction of its ex-proton and subsequent carboxylation to afford CH3C(O)CH2COO-.
