Enantiopure amidinate complexes of lutetium

Two new enantiomeric pure amidinates N,N'-bis-((R)-1-cyclohexylethyl)benzamidinate ((R)-CEBA)- and N,N'-bis-((S)-1-phenylethyl)acetamidinate ((S)-PEAA)- and their corresponding lutetium complexes [{(R)-CEBA}2Lu-μ-Cl]2 and [{(S)-PEAA}2LuCl(thf)] were synthesized.157
