Medizinisch interessante Metallchelate, III. ^99mTc‐Komplexe mit vierzähnigen Dibrenzkatechin‐Liganden

Abstract

Metal Chelates of Medical Interest, III. – 99m Tc Complexes with Tetradentate Dicatechol Ligands The dicatechol ligand bis[3‐(2,3‐dihydroxyphenoxy)propyl]‐amine hydrochloride, DIPACE ( 6 ), reduces the 99m [TcO 4 ] − ion to lower valent 99m Tc and subsequently forms a complex with the reduced 99m Tc. The structure of benzylbis[3‐(2,2‐dimethyl‐1,3‐benzodioxol‐4‐yloxy)propyl]amine ( 4 ) is determined by X‐ray crystallography.
