Synthesis, structural, and electrocatalytic reduction studies of [Pd(P 2N2)2]2+ complexes

A series of four new bis-P2N2 (P2N 2 = 1,5-diaza-3,7-diphosphacyclooctane) Pd(II) complexes were synthesized and characterized by spectroscopy, electrochemistry, and X-ray crystallography. The compounds crystallize in square planar or tetrahedrally distorted geometries and exhibit a single quasi-reversible 2e- Pd(II/0) redox couple in voltammetric studies. [Pd(PPh 2NBn2)2]2+ and [Pd(P Me2NPh2)2]2+ were tested for electrochemical CO2 reduction in the presence of excess protons and found to preferentially produce H2.

2,6-Bis(2-benzimidazolyl)pyridine as a chemosensor for fluoride ions

2,6-Bis(2-benzimidazolyl)pyridine, a neutral tridentate ligand, is employed as a chemosensor for the detection of fluoride ions. The binding of anionic guest species with this ligand is studied using UV-vis spectroscopy, fluorescence spectroscopy, and 1H NMR techniques. The results indicate that 2,6-bis(2-benzimidazolyl)pyridine can be used as a chemical shift and optical modification based sensor for the detection of fluoride ions.

Highly Enantioselective [5 + 2] Annulations through Cooperative N-Heterocyclic Carbene (NHC) Organocatalysis and Palladium Catalysis

The highly enantioselective [5 + 2] annulation of enals with vinylethylene carbonates through a cooperative N-heterocyclic carbene (NHC)/Pd catalytic system is reported. The use of a bidentate phosphine ligand was crucial to prevent coordination of the NHC organocatalyst to the active Pd catalyst. The complementary and matched combination of the chiral NHC catalyst and chiral phosphine ligand promotes high levels of both reactivity and enantioselectivity (mostly ?99% ee).

alpha-Arylation and Ring Expansion of Annulated Cyclobutanones: Stereoselective Synthesis of Functionalized Tetralones

alpha-Arylcyclobutanones display unique reactivity that makes them valuable synthetic intermediates and target molecules. We describe the preparation of alpha-aryl- and alpha-heteroarylcyclobutanones through a direct alpha-arylation reaction. Problematic fragmentations are avoided by the use of LiOtBu, which promotes a rapid but reversible self-aldol reaction that slowly releases the enolate required for alpha-arylation. We also demonstrate the ring expansion of alpha-arylcyclobutanones, a process that is highlighted in the stereoselective synthesis of 1-methoxy coniothyrinone D.

Synthesis of Polyhydroquinoline, 2,3-Dihydroquinazolin-4(1H)-one, Sulfide and Sulfoxide Derivatives Catalyzed by New Copper Complex Supported on MCM-41

Abstract: A simple, efficient and less expensive protocol for the synthesis of Cu(II) immobilized on MCM-41@Serine has been reported. This nanohybrid material was carefully characterized by Fourier transform infrared spectroscopy, scanning electron microscopy, energy-dispersive X-ray spectroscopy, inductively coupled plasma optical emission spectroscopy, X-ray diffraction, TEM, thermal gravimetric analysis, and N2 adsorption and desorption. The obtained nanostructured compound were also employed as a green, efficient, heterogeneous and reusable catalytic system for the synthesis of polyhydroquinoline, 2,3-dihydroquinazolin-4(1H)-one, sulfide and sulfoxide derivatives. High surface area, convenient recovery and reusability for several times without any significant loss of activity, the use of a commercially available, eco-friendly, cheap and chemically stable reagents, good reaction times, simple practical methodology and ease of use all make Cu(II) immobilized on MCM-41@Serine a promising candidate for potential applications in some organic reactions; makes this protocol both attractive and economically viable. Graphical Abstract: MCM-41 nanostructured was prepared via simple and versatile procedure and directly immobilized with a new type of Cu?serine complex. After characterization of this catalyst, the catalytic activity of this nanostructure compound has been investigated for the synthesis of polyhydroquinoline, 2,3-dihydroquinazolin-4(1H)-one, sulfide and sulfoxide derivatives.

The synthesis of a pseudo-rotaxane containing two metal centres has been achieved using the coordination of a ditopic organic ligand on an iridium(III) complex followed by the coordination of a copper(I) centre. Preliminary photophysical studies indicate that the excited state of the iridium is quenched by the copper unit.

Hydroarylation of 2-Aryloxybut-1-en-3-ynes via Pd/Acid-Catalyzed C?H Bond Activation: A Concise Synthesis of 2,3-Bismethylene-2,3-dihydrobenzofurans

An intramolecular exo-hydroarylation of 2-aryloxy-1,4-disilylbut-1-en-3-ynes via ortho-C?H bond activation under palladium(0) and acid catalysis was found to give 2,3-bis(silylmethylidene)-2,3-dihydrobenzofurans. The two silyl groups present probably promoted the reaction and played a key role in stabilizing the diene moiety in the product. The products readily led to functionalized condensed cycles by a Diels?Alder reaction.
