Cyclopentadienyl Free Compounds of p, d, and f Elements
(2003-07-10)One of the main objectives of this dissertation was to establish a general route to the Cp-free bis-hydrocarbyl complexes for the 4f metals, LLnR2. Taking into account both the Lewis acidic nature of the lanthanide cations ... -
Synthesis and Reactivity of Rare Earth Metals Complexes with a Nitrogen Donor Ligand. Compounds in Formal Low Oxidation States
(2003-06-30)This work presents the synthesis and characterization of dihalogeno derivatives of the rare earth metals with the monoanionic ligand L (L = Et2NCH2CH2NC(Me)CHC(Me)NCH2CH2NEt2) free of coordinating solvent molecules or ... -
Neue kovalent und ionogen aufgebaute Alkinylderivate mit Elementen der 13. Gruppe des Periodensystems
(2003-04-23)In spite of their synthetic use in organic chemistry, only a few alkynyl derivatives of group 13 metals are known in the literature and a very few of them are structurally characterized.In ... -
Syntheses, Structures, and Reactivity of Divalent Germanium and Tin Compounds Containing a Diketiminato Ligand
(2002-10-15)In this thesis, diketiminato ligands have been employed as a supporting moiety for germanium and tin compounds. The experimental results demonstrate that steric bulk and additional ... -
New Methods for the Syntheses of Amido, Imido, Nitrido and Dinitrogen Metal Complexes and Organometallic Hydrides and Oxides
(2002-04-08)New methods for the preparations of nitrogen- and oxygen-containing early transition metal compounds and imido-ansa-metal hydrides, which are difficult to achieve by other methods, have ... -
Aluminum Compounds with 3,5-Di-tert-butylpyrazolato Ligands: Syntheses, Structures and Reactions
(2002-01-11)In this doctoral thesis the bulky 3,5-Di-tert-butylpyrazolato ligand was used to synthesize 27 new organoaluminum complexes combined with halide, alkyl, acetylide groups, hydride, ... -
Non-Cp Metal complexes Supported by Nitrogen Donor Ligands
(2001-09-21)Nitrogen donor ligands of varying steric demand and different hapticities have been explored with different metals and some of the resulting compounds have been used as precursors for the ... -
Synthesis of Organoaluminum Fluorides and of an Oxo-Centered Trinuclear Carboxylate of Aluminum
(2001-08-01)In this doctoral thesis the bulky ligand Tris(trimethylsilyl)methyl was used to synthesize organoaluminum fluorides combined with alkali ions and for preparation of an oxo-centered trinuclear carboxylate of aluminum as ... -
Aluminum (I, II, III) Compounds with Multidentate Ligands: Syntheses, Reactivity, and Structures
(2001-06-01)In this dissertation, bulky multidentate ligands 1-aza-allyl, N-functionized aryl, diketiminato were used for the preparation of novel aluminum compounds in all oxidation states. The ... -
