Selective Dealkenylative Functionalization of Styrenes via C-C Bond Cleavage [PDF]

open access: yesResearch, 2020
As a readily available feedstock, styrene with about 25 million tons of global annual production serves as an important building block and organic synthon for the synthesis of fine chemicals, polystyrene plastics, and elastomers.

Titania-Catalyzed H2O2 Thermal Oxidation of Styrenes to Aldehydes

open access: yesMolecules, 2019
We investigated the selective oxidation of styrenes to benzaldehydes by using a non-irradiated TiO2−H2O2 catalytic system. The oxidation promotes multi-step reactions from styrenes, including the cleavage of a C=C double bond and the addition of an

Hydroalkylation of styrenes enabled by boryl radical mediated halogen atom transfer [PDF]

open access: yes, 2023
Organohalides are a class of widely accessible synthetic synthons, but their high reduction potential has hampered their use in radical chemistry. However, recent advances in photoredox-catalyzed halogen atom transfer (XAT) strategies have introduced ...

Hydrophosphinylation of Styrenes Catalysed by Well‐Defined s‐Block Bimetallics [PDF]

open access: yes, 2021
Advancing the applications of s-block heterobimetallic complexes in catalysis, we report the use of potassium magnesiate (PMDETA)2K2Mg(CH2SiMe3)4 [PMDETA=N,N,N’,N’,N’’-pentamethyldiethylenetriamine] for the catalytic hydrophosphinylation of styrenes ...

Electrochemical Asymmetric Diacetoxylation of Styrenes Mediated by Chiral Iodoarene Catalyst [PDF]

open access: yes, 2023
Organocatalysis with chiral iodoarenes has emerged as a powerful approach for performing enantioselective transformations, however, suffering from the need to utilize stoichiometric amounts of peroxy acids or similar high energy oxidants ...

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.

Catalytic direct hydrocarboxylation of styrenes with CO2 and H2

open access: yesNature Communications, 2022
Hydrocarboxylation of olefins with CO2 provides a useful approach for the synthesis of aliphatic carboxylic acids. Here, the authors report a rhodium-catalysed hydrocarboxylation of styrenes with CO2, using hydrogen as the terminal reductant.

Modeling Styrene−Styrene Interactions

open access: yesThe Journal of Physical Chemistry A, 2005
This study is the first step in the systematic investigation of substituted (carboxyl) polystyrene nanoparticles. Understanding the fundamental interactions between the p-carboxyl styrene monomers, where an ethyl group is used instead of a vinyl group (referenced, for convenience, as "p-carboxyl styrene"), provides the basic information needed to ...

Random copolymer blends of styrene, para-fluoro styrene and ortho-fluoro styrene [PDF]

open access: yesPolymer, 1993
This study completes the investigation of the phase behaviour of polymer blends involving styrene (S), ortho-fluoro styrene (oFS) and para-fluoro styrene (pFS). As before, due to the proximity of the glass transition temperatures of most blends investigated, the miscibility or immiscibility is established using the alternative thermal analysis method ...

Anti-Markovnikov hydro(amino)alkylation of vinylarenes via photoredox catalysis

open access: yesNature Communications, 2021
Many useful chemical scaffolds include carbon or nitrogen substitutions at two or three atoms away from benzene. Here, the authors show a unified hydroalkylation and hydroaminoalkylation protocol to access these structures via a regioselective ...
