The first chiral amidinate borohydride rare earth compounds and compounds based on (S)-HPEBA ((S,S)-N,N-bis-(1-phenylethyl)benzamidine) ligand were reported by Roesky et al. To continuing this work, the new chiral ligand (S)-HNEBA ((S,S)-N,N-bis-(1-naphthylethyl)benzamidine) were synthesized. The corresponding amidinate metal complexes were successfully obtained by amine elimination. The luminescent and magnetic properties of rare earth compounds were studied. Alkaline earth metal compounds have been extensively studied as catalysts in synthetic chemistry. However, chiral amidinate alkaline earth metal complexes have never been reported. Chiral amidinate ligand (S)-HPEBA was introduced into the coordination chemistry of the alkaline earth metal as well as divalent lanthanides, their catalytic activities in hydrophosphination have been investigated. The Ba compound showed high catalytic activities in the hydrophosphination reaction. Moreover, since rare earth metal COT complexes exhibit excellent SMM behavior, it is of great interest to study the magnetic behavior of COT amidinate complexes. Thus, amidine ligand (S)-HPEBA and (S)-HPETA are introduced into the corresponding COT amidinate complexes for magnetic properties studies. The Er Compound exhibited typical field-induced SMM behavior. Furthermore, inspired by the promising application of lanthanide SMMs and the research of SMMs based on sandwich type lanthanide complexes, a series of novel sandwich type complexes comprising of Pc and COT ligand were designed and synthesized.

Defined metalmethyl compounds were first reported in the middle of the 19th century and the interest in metal alkyls is still growing. So far 26 out of 60 non-radioactive metals have been found to form homoleptic isolable methyl componds [M(CH3)x] (x = 1-6). The report on the successful synthesis of dimethylcalcium [CaMe2]n triggered further research on the often discussed parallels of alkaline-earth metals and the divalent rare-earth-metals Sm2+, Eu2+ and Yb2+. Dimethylytterbium [YbMe2]n could be accessed via the reaction of the donor-free precursor [Yb{N(SiMe3)2}2]2 with methyllithium. [YbMe2]n was fully characterized and follow-up chemistry was investigated. Noteworthily, the protonolysis reaction of [YbMe2]n with protic hydrotris(3-tBu-5-Me-pyrazolyl)borate HTptBu,Me gave the first terminal Yb2+ methyl complex [TptBu,MeYb(CH3)(thf)] providing direct evidence of the existence of the methyl precursor. Further, the synthesis of the divalent dimethyl compounds of samarium and europium was attempted. The focus of the second part of this work was the synthesis of new rare-earth-metal imide complexes. Through a one-pot salt-metathesis reaction (LnI2(thf)2 + KTptBu,Me + KNHR with Ln = Sm, Eu, Yb and R = 2,6-iPr-C6H3, 2,6-Me-C6H3, 3,5-CF3-C6H3, SiPh3) or a protonolysis approach (TptBu,MeYb(N(SiMe3)2) + H2NR, R = R = 2,6-iPr-C6H3, 3,5-CF3-C6H3, SiPh3) efficient access to amide complexes [TptBu,MeYbNH(R)(thf)x] (R = 2,6-iPr-C6H3, 2,6-Me-C6H3, 3,5-CF3-C6H3, SiPh3) could be gained. All synthesized complexes were fully characterized and their reactivity toward Lewis acids and bases as well as their redox chemistry was further investigated. The obtained compounds are potential precursor complexes for the synthesis of rare-earth-metal imide complexes.
