Biocatalytic nanoparticles for the stabilization of degassed single electron transfer-living radical pickering emulsion polymerizations.
TL;DR: Lignin nanoparticles coated with chitosan and glucose oxidase enable efficient stabilization of Pickering emulsion and in situ enzymatic degassing of single electron transfer-living radical polymerization (SET-LRP) without extraneous hydrogen peroxide scavengers.

Polyacrylates Derived from Biobased Ethyl Lactate Solvent via SET-LRP
Nabil Bensabeh,Adrian Moreno,Adrià Roig,Olivia R. Monaghan,Juan C. Ronda,Virginia Cádiz,Marina Galià,Steven M. Howdle,Gerard Lligadas,Virgil Percec +9 more
TL;DR: The near-quantitative monomer conversion and high bromine chain-end functionality, demonstrated by matrix-assisted laser desorption ionization time-of-flight analysis, further allowed the preparation of innovative biobased block copolymers containing rubbery poly(ethyl lactate acrylate) poly(ELA) sequences.

The reaction of dimethylsulfoxide and 5-dimethyl aminonaphthalene-1- sulfonyl chloride
TL;DR: In this paper, the reaction of dimethyl sulfoxide and 5-dimethyl aminonaphthalene-1- sulfonyl chloride was studied under the conditions of a pseudo-unimolecular reaction with the dimethylsulfoxide in excess.

Me6-TREN/TREN Mixed-Ligand Effect During SET-LRP in the Catalytically Active DMSO Revitalizes TREN into an Excellent Ligand.
Devendra S. Maurya,Ayesha Malik,Xiaojing Feng,Xiaojing Feng,Nabil Bensabeh,Gerard Lligadas,Virgil Percec +6 more
TL;DR: The catalytic activity of DMSO facilitates the much less expensive TREN to act as a very efficient ligand that is competitive with Me6-TREN and with the mixed-ligand and revitalizes TREN into an excellent ligand.

TL;DR: It is reported that polarsolvents such as H(2)O, alcohols, dipolar aprotic solvents, ethylene and propylene carbonate, and ionic liquids instantaneously disproportionate Cu(I)X into Cu(0) and Cu(II)X(2), facilitating an ultrafast LRP in which the free radicals are generated by the nascent and extremely reactive Cu( 0) atomic species.

Searching for green solvents
TL;DR: In this article, the authors present four grand challenges in the field of green solvents: finding a sufficient range of green solvent, recognizing whether a solvent is actually green, finding an easily-removable polar aprotic solvent and eliminating distillation.

Single-Electron Transfer and Single-Electron Transfer Degenerative Chain Transfer Living Radical Polymerization
Brad M. Rosen,Virgil Percec +1 more
TL;DR: In this article, the authors present the latest progress in two related polymerization methodologies that rely on singleelectron transfer (SET), single-electron-transfer degenerative chain transfer living radical polymerization (SET-DTLRP), and single-Electron Transfer Living Radical Poly(SET-LRP) for the synthesis of tailored polymers.
