Tertiary amine solvents having switchable hydrophilicity
Philip G. Jessop,Lisa M. Kozycz,Zahra Ghoshouni Rahami,Dylan Schoenmakers,Alaina R. Boyd,Dominik Wechsler,Amy M. Holland +6 more
TL;DR: Several tertiary amines serve as switchable-hydrophilicity solvents, meaning that they are hydrophobic, having very low miscibility with water when under air but hydrophilic, having complete miscibility in an atmosphere of CO2 as mentioned in this paper.

Substitutions by nucleophilic free radicals: A new general reaction of heteroaromatic bases
TL;DR: In this article, the substitution of protonated heteroaromatic bases by nucleophilic carbon-centered radicals has been developed as one of the most general reactions in the heterocyclic series; its great interest results from the fact that it reproduces most of the numerous aspects of the Friedel-Crafts aromatic substitution, but with opposite reactivity and selectivity.
Journal ArticleDOI
Design and evaluation of switchable-hydrophilicity solvents
TL;DR: Switchable-hydrophilicity solvents (SHSs) as discussed by the authors can switch reversibly between one form that is miscible with water to another that forms a biphasic mixture with water.

Kinetics and mechanisms of reactions of organic cation radicals in solution
Ole Hammerich,Vernon D. Parker +1 more
TL;DR: In this article, two mechanisms are proposed for the dimerization of cation radicals of anisoles and related compounds, termed as radical-substrate coupling (RSC) and radical-surface coupling (RRD).

α-Hydroxyalkylation of heteroaromatic bases by alcohols and hydroxylamine-O-sulphonic acid
TL;DR: In this paper, the homolytic decomposition of hydroxylamine-O-sulphonic acid in alcoholic solvents was investigated in the presence or absence of protonated heteroaromatic bases and Fe(II) salt.

TL;DR: In this article, it was shown that strong polar effects were observed not only with strongly polar radicals, but also with moderately polar radicals such as carbon-free radicals, if the reacting substrate has a marked polar nature.
