Amide-Amine Replacement in Indole-2-carboxamides Yields Potent Mycobactericidal Agents with Improved Water Solubility

Indolecarboxamides are potent but poorly soluble mycobactericidal agents. Here we found that modifying the incipient scaffold by amide-amine substitution and replacing the indole ring with benzothiophene or benzoselenophene led to striking (10-20-fold) im

Synthetic method for preparing aryl methyl selenide compound from selenium methyl Burnt salt and aryl boronic acid

The invention relates to a synthesis method for preparing aryl methyl selenide from selenium methyl Burnt salt and aryl boronic acid. The aryl methyl selenide compound is obtained through oxidative coupling reaction in an organic solvent under the condition of oxygen by taking selenium methyl Burnt salt and aryl boronic acid as reaction raw materials under the common synergistic catalytic action of a transition metal copper catalyst, silver salt, a ligand and alkali. According to the method, the tasteless and stable selenium methyl Burnt salt is used as a selenium methylation reagent, the yield and purity of the product are high, a synthetic route and method are developed for preparation of the aryl methyl selenide compound, and the method has a good application potential and research value.

Symmetric Mixed Sulfur–Selenium Fused Ring Systems as Potential Materials for Organic Field-Effect Transistors

A reliable synthetic protocol toward a series of fused chalcogenopheno[1]benzochalcogenophene (CBC) building blocks was developed based on a Fiesselmann reaction. The obtained CBC units were applied in McMurry and Stille coupling reactions toward symmetric regioisomeric ene-linked dimers. These π-conjugated compounds were characterized regarding their photophysical and electrochemical properties and proved to be materials with reduced HOMO–LUMO gaps compared to their sulfur-based analogues. Single-crystal X-ray diffraction experiments revealed strong intermolecular selenium–selenium and selenium–carbon interactions depending on the position and number of incorporated selenium atoms. Good field-effect transistor performance with charge carrier mobilities up to 4×10?3 cm2 V?1 s?1 and high on/off ratios could be observed.

Mild generation of selenolate nucleophiles by thiol reduction of diselenides: Convenient syntheses of selenyl-substituted aryl aldehydes

Various selenyl-substituted aryl aldehydes were obtained using dithiothreitol (DTT) as a reducing agent for diselenides in the presence of a base. For electron-deficient haloaryl aldehydes, a weak base, such as K 2CO3, performed well. However, for electron-rich haloaryl aldehydes, a stronger base, such as 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU), was required for successful substitution. The selenyl-substitution of heteroaryl substrates were also investigated to obtain satisfactory yields of the desired products.

Synthesis, characterization and coordination properties of bis(alkyl)selenosalen ligands

New bis (alkyl) selenosalen podand ligands having Se2N2 donor sites have been synthesized by the condensation of unsymmetrical o-formylphenyl alkyl selenide (1-3) with ethylenediamine. The reaction of bis(alkyl)selenosalen podands with Pd(II) and Pt(II) afforded selenoether-selenolate coordination complexes 7-10via cleavage of one of the two Se-C(alkyl) bonds of bis(alkyl)selenosalen podands upon complexation. DFT calculations revealed that the cleavage of Se-C(alkyl) bonds occurred possibly via SN2 mechanism instead of a sequence of oxidative addition and reductive elimination reactions. The spectral data and elemental analyses confirmed the formation of selenoether-selenolate complexes. The structures of the podands N,N′-bis[(2-methylseleno)phenylmethylene]-1,2-ethanediamine (4), N,N′-bis[(2-decylseleno)phenylmethylene]-1,2-ethanediamine (5) and the selenoether-selenolate complex 8 have been determined by single crystal X-ray diffraction analysis. The crystal structure of 5 showed Se...H interaction with a ladder like 3D supramolecular arrangement via interdigitation of long alkyl chains. Comparison of crystal packing of podands 4 and 5 indicates that the alkyl chain length has significant impact on the crystal packing. The platinum selenolate complex 8 shows a square planar arrangement around the Pt centre, where the Se atoms in the selenolate and the selenoether have nearly equal Pt-Se bond length.
