RESUMO

The PhI(OAc)2-promoted 1,2-transfer reaction between allylic alcohols and thiophenols, conducted in an argon atmosphere, has proven to be effective in producing ß-carbonyl sulfides from 1,1-disubstituted allylic alcohols in high yields. This method offers a fast and efficient way to synthesize ß-carbonyl sulfides, which are valuable intermediates in organic synthesis. This discussion focuses on the effects of the oxidizer, temperature, and solvent on the reaction. A proposed tentative mechanism for this reaction is also discussed.

RESUMO

The photoredox-catalyzed decarboxylative cross-coupling reaction of aryl acetic acids and aryl nitriles has been achieved under an argon atmosphere in high yields. This method provides a fast way to obtain prevalent aryl acetic acids from an abundant natural source. A tentative radical mechanism has been proposed.

RESUMO

The title compound, C17H13FN2, was synthesized as a potential ligand for the construction of metal-organic frameworks. The two indole motifs present two potential coordination modes. It crystallizes in the ortho-rhom-bic system with space group P212121. The dihedral angle between the fused ring systems is 68.77 (10)°. Weak F⋯H inter-actions are observed in the crystal.

RESUMO

A facile and efficient aerobic oxidative (4 + 2)-cyclization/aromatization/lactonization tandem reaction of N-aryl glycine esters with propargyl alcohols to access quinoline-fused lactones is reported. The reaction can be extended to homopropargylic alcohols too. The transformation is straightforward to perform under mild conditions and scalable, and both reaction components are readily available.

RESUMO

We report a visible-light induced redox-neutral decarboxylative cross coupling reaction of indole-3-acetic acid NHPI esters with indoles using a Ru photosensitizer to deliver a wide range of symmetrical and unsymmetrical 3,3'-bisindolylmethane derivatives. Furthermore, the reaction is readily adapted to the preparation of a wide variety of diarylmethane derivatives.

RESUMO

A one-dimensional Ag(I) coordination complex, catena-poly[[silver(I)-µ-{2-[2-(pyridin-4-yl)-1H-benzimidazol-1-ylmethyl]phenol-κ(2)N(2):N(3)}] perchlorate monohydrate], {[Ag(C19H15N3O)]ClO4·H2O}n, was synthesized by the reaction of 2-[2-(pyridin-4-yl)-1H-benzimidazol-1-ylmethyl]phenol (L) with silver perchlorate. In the complex, the L ligands are arranged alternately and link Ag(I) cations through one benzimidazole N atom and the N atom of the pyridine ring, leading to an extended zigzag chain structure. In addition, the one-dimensional chains are extended into a three-dimensional supramolecular architecture via O-H···O hydrogen-bond interactions and π-π stacking interactions. The complex exhibits photoluminescence in acetonitrile solution, with an emission maximum at 390 nm, and investigation of the thermal stability reveals that the network structure is stable up to 650 K.

RESUMO

In the mononuclear title complex, [Cu(C(16)H(19)N(5))(2)](NO(3))(2), the Cu(II) ion is located on a twofold rotation axis and is six-coordinated by six N atoms from two 2-[bis-(3,5-dimethyl-1H-pyrazol-1-yl)meth-yl]pyridine ligands, forming a distorted octa-hedral geometry. In the crystal, mol-ecules are linked by weak C-H⋯O inter-actions.

RESUMO

The Zn(II) atom in the title complex, [ZnCl(2)(C(8)H(12)N(4))], is coordinated by two Cl atoms and three N atoms of the N-[1-(pyrazin-2-yl)ethyl-idene]ethane-1,2-diamine ligand, and displays a distorted square-pyramidal geometry with the apical position occupied by a Cl atom. In the crystal, inter-molecular N-H⋯Cl and C-H⋯Cl hydrogen bonds link the mol-ecules into a three-dimensional framework.
