Abstract

A new ligand, 3-(1-naphthyl)-2, 4-pentanedione, was prepared. Concentration proton- dissociation constants of 3-aryl-2, 4-pentanedione (aryl group; phenyl, 2, 4-dinitrophenyl, and 1-naphthyl) and concentration stability constants of some bivalent metal chelates of 3- aryl-2, 4-pentanedione were determined in a 75% v/v 1, 4-dioxane–water medium containing 0.05 mol dm− 3 sodium perchlorate by a pH-titrimetric method. The ...
