Copper-Catalyzed Annulation of Oxime Acetates with α-Amino Acid Ester Derivatives: Synthesis of 3-Sulfonamido/Imino 4-Pyrrolin-2-ones

A copper-catalyzed annulation of oxime acetates and α-amino acid ester derivatives for the easy preparation of 4-pyrrolin-2-ones bearing a 3-amino group has been developed. This process features the oxidation of amines with oxime esters as the internal oxidant to produce the active 1,3-dinucleophilic and 1,2-dielectrophilic species concurrently. The subsequent nucleophilic cyclization realizes the efficient construction of 4-pyrrolin-2-one derivatives.

Structures, luminescent and magnetic properties of three dinuclear lanthanide complexes: Magnetic refrigeration and single-molecule magnet behaviour

Three dinuclear lanthanide complexes: {[Ln2(L)2(pbd)4]·2CH3CN} (Ln = Eu (1), Gd (2), Dy (3); HL = 2-(hydroxyimino)-N′-(pyridin-2-ylmethylene)propanehydrazonic acid, pbd = 1-phenylbutane-1,3-dione) were fabricate

Exploring Tuning of Structural and Magnetic Properties by Modification of Ancillary β-Diketonate Co-ligands in a Family of Near-Linear Tetranuclear DyIII Complexes

Three tetranuclear DyIII complexes, [Dy4(LH)2(CH3OH)4(acac)6] (1), [Dy4(LH)2(CH3OH)4(hmacac)6]·2CH3OH (2), and [Dy4(LH)2(CH3OH)4(dpacac)6]·2CHCl3·2CH3OH·2H2O (3), have been synthesized and characterized [LH4 = (2E,N′E)-N′-(2,3-dihydroxybenzylidene)-2-(hydroxyimino)propanehydrazide; acacH = acetylacetone; hmacacH = 2,2,6,6-tetramethyl-3,5-heptanedione; dpacacH = dibenzoylmethane]. The structural elucidation of these complexes reveals two types of DyIII centers in terms of the number of ancillary β-diketonate co-ligands coordinated to the metal centers. Detailed magnetic studies have been carried out on 1-3 which reveal a slow relaxation of magnetization at low temperatures. The relaxation of complexes 2 and 3 is distributed in three temperature ranges: lower temperature process, transition range, and higher temperature process. In the higher temperature range, the best fitting of the data for 2 yields τ0 = (6.3 ± 3.6) × 10-6 s and Ueff = (23.8 ± 4.0) K, and for 3, τ0 = (9.4 ± 5.9) × 10-6 s, Ueff = (29.0 ± 6.3) K.
