A novel ammonium iodide-induced sulfonylation of alkenes with DMSO and water toward the synthesis vinyl methyl sulfones is described. The process proceeded smoothly under metal-free conditions high stereoselectivity good functional group tolerance. reaction mechanism was revealed to proceed through a domino oxidation elimination after radical addition alkenes.

A novel synthesis recipe for β-alkoxy methyl sulfides was developed via NH4I-mediated three-component oxysulfenylation reaction of styrenes with DMSO and alcohols. This method features simple operation readily available starting materials, it provides an alternative sulfenylating agent generated from reactions.

With atmospheric oxygen as the oxidant, a novel copper(I)-catalyzed synthesis of aryl methyl sulfones from halides and widely available DMSO is described. The procedure tolerates with various functional groups (such methoxy, acetyl, chloro, fluoro nitro groups), which could afford in moderate to high yields. copper-catalyzed aerobic oxidation cleavage/formation C–S bond are key steps for this transformation.

Abstract Three polystyrene‐supported N‐heterocyclic carbene–silver complexes [PS‐NHC‐Ag(I)] and a carbene–copper complex [PS‐NHC‐Cu(I)] catalyst were synthesized characterized by elemental analysis, Fourier transform infrared spectroscopy, inductively coupled plasma‐atom emission spectrometer, thermogravimetric analysis scanning electron micrographs. The catalytic activity of the supported catalysts was investigated for reaction propargylic alcohols carbon dioxide. PS‐NHC‐Cu(I) showed no to...

A novel method toward synthesis of sulfonamides and β-arylsulfonyl enamines has been developed via I2/TBHP mediated C–N C–H bond cleavage tertiary amines, which features highly selective formation two different target products depending on the reaction solvent. The experimental results reveal that H2O as solvent could effectively achieve to produce due participating in process where plays a dual role. Differing from H2O, organic solvents (such dimethyl sulfoxide) promote amines yield enamines.

A novel carbon dioxide triggered and copper-catalyzed domino reaction for the efficient synthesis of highly substituted 3(2H)-furanones from readily available nitriles propargylic alcohols has been developed. Carbon is a prerequisite achieving present catalytic transformation, one oxygen atoms incorporated into 3(2H)-furanones. Nitriles not only act as solvent but also reactant; copper salts play dual roles activating both nitriles.

The formation of carbon-carbon and carbon-oxygen bonds continues to be an active challenging field chemical research. Nanoparticle catalysis has attracted considerable attention owing its environmentally benign high activity toward the reactions. Herein, we described a novel effective nano-Cu(2)O-catalyzed one-pot domino process for regioselective synthesis α-carbonyl furans. Various electron-deficient alkynes with 2-yn-1-ols underwent this smoothly in moderate good yields presence air at...

Abstract The economical consideration of using an electrocatalyst in energy‐related field, composed non‐precious/sustainable elements is quite noteworthy. In this work, the phosphorus(V) complex tris‐(pentafluorophenyl)corrole [(TPFC)P V (OH) 2 ] was reported as for hydrogen evolution reaction (HER). electrochemical studies revealed that HER experienced a ECEC pathway (E: electron transfer step, C: chemical step), and possible intermediate [P ]−H species suggested.
