Correia, Isabel; Pessoa, João Costa; Duarte, M. Teresa; Piedade, M. Fátima Minas da; Jackush, Tamás; Kiss, Tamás; Castro, M. Margarida C. A.Several sal2en-type reduced Schiff bases have been prepared from the reaction of 2 equiv. of salicylaldehyde (or derivatives) with ethylenediamine followed by reduction with NaBH4 and subsequently characterised. The water-soluble ligands (SO3-sal)2en and R(SO3-sal)2en (SO3-sal = salicylaldehyde-5-sulphonate) have been studied by pH potentiometry and 1H NMR spectroscopy and the protonation constants of R(SO3-sal...
