Cage Effect on Oxidation of Dimethyl Sulfoxide via Pd2L4 Prolate Spheroids

Self-assembly of PdX2 (X? = NO3 ?, BF4 ?, and CF3SO3 ?) with 2,6-bis(4?-nicotinamidephenoxy)naphthalene (L) forms a series of [Pd2L4]X4 prolate spheroids. The O donors of two Me2SO molecules within the prolate spheroid cage are oriented toward the Pd(II) metal centers. In the presence of H2O2, the nestled Me2SO within the cage is efficiently oxidized to Me2SO2 at room temperature.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Product Details of 21797-13-7, you can also check out more blogs about21797-13-7

Biphasic Aqueous Reaction Conditions for Process-Friendly Palladium-Catalyzed C-N Cross-Coupling of Aryl Amines

We herein describe a method for palladium-catalyzed C-N cross-coupling of aryl amines and aryl halides in a biphasic reaction medium composed of 2-methyltetrahydrofuran (MeTHF) and water. By effective solubilization of the inorganic base used, common challenges associated with the scalability of Buchwald-Hartwig aminations using inorganic bases were circumvented. The mildly basic nature of the reaction conditions was highlighted by the facile coupling of a base-sensitive substrate, which could be converted to the corresponding product with a high level of crude purity. The method is operationally simple and displays an improved safety and sustainability profile compared with many alternative strategies for large-scale Buchwald-Hartwig amination. Relying on a commonly available dialkylbiarylphosphine ligand, this approach was applied to three clinically relevant C-N cross-coupling reactions on the hecto- to kilogram scale.

Palladium-catalyzed cross-coupling of various phosphorus pronucleophiles with chloropyrazines: Synthesis of novel Am(iii)-selective extractants

Palladium-catalyzed cross-coupling of (di)chloropyrazines with phosphorus pronucleophiles in the presence of a base gave the phosphorylated pyrazines in 81-95% yields. Based on this methodology a series of appropriately functionalized pyrazines was prepared as potential extractants of trivalent cations from highly acidic nuclear waste. A few hydrophilic derivatives exhibited a very good selectivity for Am3+ over Eu3+ with separation factors up to 40 at pH 1 at 0.01 mol L-1 ligand concentration.

General Synthesis of Alkenyl Sulfides by Palladium-Catalyzed Thioetherification of Alkenyl Halides and Tosylates

The cross-coupling reaction of alkenyl bromides with thiols catalyzed by palladium complexes derived from inexpensive dppf ligand is reported. These reactions occur under low catalyst loading and in high yields and display wide scope, including the coupling of bulky thiols and trisubstituted bromoolefins, and functional group tolerance. In addition, the thioetherification of less reactive chloroalkenes and, for the first time, alkenyl tosylates was accomplished using a catalyst generated from CyPFtBu alkylbisphosphine ligand.

Development of a palladium-catalyzed alpha-arylation of cyclopropyl nitriles

1,1-Disubstituted aryl cyclopropyl nitriles are useful moieties in biologically active compounds and provide access to a range of cyclopropyl derivatives. Herein, we describe the development of a palladium-catalyzed alpha-arylation of cyclopropyl, cyclobutyl, and cyclopentyl nitriles that affords these functional groups in one step from a variety of aryl bromides in good to excellent yields. Furthermore, we demonstrate the transformation of aryl cyclopropyl nitriles into aryl trifluoromethyl cyclopropanes.
