Metal-free visible-light-enabled vicinal trifluoromethyl dithiolation of unactivated alkenes

open access: yesBeilstein Journal of Organic Chemistry, 2021
The difunctionalization of alkenes involving a trifluoromethylthio group (SCF3) for the conversion of versatile and readily available olefins into structurally more complex molecules has been successfully studied.

From‐Neutral‐to‐Neutral Reductive Radical Coupling of Non‐Activated Alcohols and Styrenes

open access: yesChemistryEurope, 2023
A reductive radical coupling reaction between non‐activated aliphatic alcohols and styrenes has been discovered through the use of low‐valent Ti‐mediated C−O bond homolysis.

Alkene-oxo and alkene-alkene coupling on Pt(II) [PDF]

open access: yes, 2021
Tetranuclear Pt(II) oxo-complex [(COD)4Pt4([mu]3-O)2Cl2](BF4)2 (1) (COD = 1,5- cyclooctadiene) was found to readily react with a variety of alkenes (ethylene, norbornene, propylene and cyclopentene). The most significant discovery resulted from the norbornene reaction, which gave platinaoxetane [(COD)2Pt2(OC7H10)Cl]BF4 (4), the first metallaoxetane ...

Trifluoromethanesulfonamide vs. Non-Fluorinated Sulfonamides in Oxidative Sulfamidation of the C=C Bond: An In Silico Study

open access: yesMolecules, 2020
A theoretical analysis of the reaction of oxidative sulfamidation of several alkenes was performed in order to explain the various experimental observations and different reactivity of triflamide and non-fluorinated sulfonamides.

Visible-light promoted atom transfer radical addition-elimination (ATRE) reaction for the synthesis of fluoroalkylated alkenes using DMA as electron-donor [PDF]

open access: yes, 2020
Here, we describe a mild, catalyst-free and operationally-simple strategy for the direct fluoroalkylation of olefins driven by the photochemical activity of an electron donor-acceptor (EDA) complex between DMA and fluoroalkyl iodides.

Iron(III)-Mediated Rapid Radical-Type Three-Component Deuteration of Quinoxalinones With Olefins and NaBD4

open access: yesFrontiers in Chemistry, 2020
Iron(III)-promoted rapid three-component deuteration of quinoxalinones with olefins and NaBD4 is reported for the first time, which provides a novel, economic, and efficient method for the rapid synthesis of deuterated quinoxalinones.

Glycerol as a cheap, safe and sustainable solvent for the catalytic and regioselective β,β-diarylation of acrylates over palladium nanoparticles [PDF]

open access: yes, 2010
Herein we show that glycerol can be considered as a promising cheap and green solvent for the regioselective β,β-diarylation of alkenes. Whereas this reaction is generally catalyzed under an inert atmosphere by expensive phosphine or carbene-palladium ...

Iodine-Mediated Alkoxyselenylation of Alkenes and Dienes with Elemental Selenium

open access: yesMolecules, 2022
A one-pot synthesis of linear and cyclic β-alkoxyselenides is developed through the iodine-mediated three-component reaction of elemental selenium with alkenes (dienes) and alcohols.

Recent Advances in the Synthetic and Mechanistic Aspects of the Ruthenium-catalyzed Carbon-heteroatom Bond Forming Reactions of Alkenes and Alkynes [PDF]

open access: yes, 2011
The group’s recent advances in catalytic carbon-to-heteroatom bond forming reactions of alkenes and alkynes are described. For the C–O bond formation reaction, a well-defined bifunctional ruthenium-amido catalyst has been successfully employed for the ...
