Copper-catalyzed direct oxidative C(sp 2 )-H α -sulfenylation of enaminones with disulfides or thiophenols: Synthesis of polyfunctionalized aminothioalkenes
摘要:
A copper(II)-catalyzed protocol for the construction of aminothioalkenes has been achieved that is based on the reaction of enaminones with disulfides/thiophenols in the presence of tert-butyl hydroperoxide (TBHP) to give good to excellent yields. This study provides a new strategy for the formation of C (sp(2))-S bonds via direct alpha-sulfenylation of C(sp(2))-H bonds. (C) 2018 Elsevier Ltd. All rights reserved.

Palladium(II) complexation of ambidentate cis-s-cis-enaminones: synthesis of some bis(4-anilinopent-3-en-2-onato)- and bis(3-amino-1-phenylbut-2-en-1-onato)-complexes of palladium(II) and X-ray crystal structure of bis[4-(2-bromoanilino)pent-3-en-2-onato]palladium(II)
cis-s-cis-enaminone structure behave as bidentate ligands for PdII to yield stable yellow complexes, the structures of which have been determined as bis(4-anilinopent-3-en-2-onato)- and bis(3-amino-1-phenylbut-2-en-1-onato)-complexes of palladium(II), respectively. To establish the structure of the complex in the solid state, X-ray crystalstructure analyses have been carried out on bis[4-(2-bromoanili

A novel and reusable magnetic nanocatalyst developed based on graphene oxide incorporated strontium nanoparticles for the facial synthesis of β-enamino ketones under solvent-free conditions
A novelmagnetic SrFeGO nanocatalyst (NC) was synthesized through a simple sol–gel technique by introducing strontium and iron oxide nanoparticles onto graphene. The synthesized NC was characterized using FT‐IR and FE‐SEM. Subsequently, the catalytic activity of SrFeGO was tested in a reaction between β‐dicarbonyl compounds and aniline derivatives to gain β‐enamino ketone derivatives under solvent‐free
