A tetranuclear CuII2DyIII2 coordination cluster as a Suzuki (C–C) coupling reaction promoter

Abstract

The air stable and high yielding tetranuclear coordination cluster [CuII2DyIII2L4(NO3)2(CH3CN)2]·2(CH3CN) promotes the Suzuki coupling reaction of phenylboronic acid with substituted aryl halides under environmentally benign conditions.

Chirality and Magnetic Properties of One‐dimensional Ln (Ln = Gd, Dy) Polymers

“…In the light of magnetic properties, the lanthanide ions, as evidenced by the rising research, have attracted plentiful attention on establishment both single‐chain magnets (SCMs) and single‐molecule magnets (SMMs) as well as magnetocaloric effect (MCEs),, on account of the magnetic anisotropy or the large‐spin multiplicity of the spin ground‐state , . To the best of our knowledge, lanthanide ions own the individual 4f electronic structures, resulting high and changing coordination numbers, large magnetic effects and so on, which is favored for the potential applications in magnetic fields, etc , .…”

Solvent-Free Synthesis and Key Intermediate Isolation in Ni2Dy2 Catalyst Development in the Domino Ring-Opening Electrocyclization Reaction of Furfural and Amines

“…[12][13][14][15][16][17] We initiated a project toward the development of well-characterized 3d/4f bimetallic coordination entities that remain intact in solution and efficiently promote a series of organic transformations. [18][19][20][21][22] The precise topology of these entities, the partially saturated coordination geometry of each metal center and in particular the distance separating the metals have been suggested to be key parameters for efficient catalysis. 12,13 The presence of two different metals with significantly different binding selectivity (3d vs 4f), promotes the selective substrate binding; this is a significant advantage compared to homometallic catalysts.…”

Trinuclear Lanthanide Coordination Clusters: Single‐Molecule‐Magnet Behavior and Catalytic Activity in the Friedel‐Crafts Alkylation Reaction

“…These were essentially significant approaches with the metal salt producing moderate to good yields of the products. Recently, Kostakis and his group introduced heteronuclear coordination clusters (3 d/4 f metals) as potential catalysts for important organic transformations such as Friedel‐Crafts alkylation, Domino reaction, Michael Addition, Petasis Borono‐Mannich multicomponent Reaction and Suzuki coupling reaction . Although homonuclear coordination clusters of 3 d metal ions have been proven to be an effective catalyst in many organic reactions, lanthanide coordination clusters have not been explored yet.…”

“…Recently, Kostakis and his group introduced heteronuclear coordination clusters (3 d/4 f metals) as potential catalysts for important organic transformations such as Friedel-Crafts alkylation, [26] Domino reaction, [27] Michael Addition, [28] Petasis Borono-Mannich multicomponent Reaction [29] and Suzuki coupling reaction. [30] Although homonuclear coordination clusters of 3 d metal ions have been proven to be an effective catalyst in many organic reactions, [31,32] lanthanide coordination clusters have not been explored yet. Among the above mentioned organic reactions, Friedel-Crafts alkylation leading to bis(indolyl)alkanes can be considered as an important reaction because these organic compounds can be found in many biologically active natural products and they are also an useful moiety in the design of drugs.…”
