Summary
The thioamido group, when present as -NH · CS- in five-membered rings, reduces copper(II) to copper(I) in methanol. Evidence for CuL2X2 intermediates are obtained avoiding the reduction by N-alkylation. Crystalline CuL2X2 complexes have been obtained for L =N,N′-dimethyl- andN,N′-diethyl-1,3-imidazolidine-2-thione and X = Cl, Br.
