Fluorinated lithium 1,3-diketonates as reagents to modify podands and crown-ethers

Bidentate and Tetradentate β‐Aminovinyl Trifluoromethylated Ketones and Their Copper(II) Complexes: Synthesis, Characterization and Redox Chemistry

“…[6][7][8] β-Aminovinyl ketones with a fluoroalkyl moiety are interesting organic precursors that can be decorated in a number of useful synthetic sequences to produce diverse molecular entities with specific applications. [1,[9][10][11][12][13][14][15][16][17][18][19][20][21] Their potentially broad coordination chemistry [21][22][23][24][25][26][27][28][29] combined with appropriate organic functionalities make them attractive for the design of a new generation of original materials with potential in catalysis, molecular magnetism and therapeutic applications. A series of fluorinated enaminones that bear two independent coordination centres have been obtained, and the crystal structure of a Cu II complex has been reported.…”

“…A series of fluorinated enaminones that bear two independent coordination centres have been obtained, and the crystal structure of a Cu II complex has been reported. [21] The crystal structure of a Mn II complex with a trifluoromethylated en- For all the complexes, a stable Cu I species was evidenced by a quasireversible reduction step at potentials from -0.48 to -1.08 V (potential standards E 0 ), but the most stable Cu I species originated from the Cu II complex with the tetradentate ligand. UV/Vis absorption spectra revealed no major differences between the ligands and their Cu II complexes.…”

Copper(II) Cubane Complexes Built from Electro‐ and Photosensitive β‐Aminovinyl Trifluoromethyl Ketone Ligands

“…Our research is currently devoted to the elaboration of ligands able to bring additional properties to the magnetic core with the expectation that both properties could interact cooperatively. [8,[16][17][18][19][20][21][22][23][24][25][26] Their potential for diverse coordination chemistry [27][28][29][30][31][32][33][34][35][36] combined with appropriate pendant organic functionalities (a photosensitive unit, a stable radical, an electron donor, a luminescent unit or a biomolecule) make them attractive for the design of new generations of original materials. [8] On the other hand, their ability to coordinate a large panel of transition-metal ions have led to the preparation of a number of metallomesogens with interesting liquid-crystal properties [9][10][11][12] or highly-active catalysts for olefin polymerization, including fluorinated enaminones.…”

Metal and Boron Derivatives of Fluorinated Cyclic 1,3-Dicarbonyl Compounds

“…Fluorinated 1,3-dicarbonyls are of special importance in this context: their versatility, high reactivity and preparative availability make them often the starting compounds of choice [3 -5]. At the same time, fluorinated 1,3-dicarbonyl enolates (salts or complexes) [4 -7] give frequently better results, when compared to the related 1,3-dicarbonyl compounds, and are as a rule more convenient in handling [5,6,8]. In this paper we report the synthesis and several striking synthetic applications of metal derivatives of cyclic fluorinated 1,3-dicarbonyl compounds which were collected in our groups during studies in this field [9 -14].…”
