Diastereodivergent nucleophile–nucleophile alkene chlorofluorination
Nature ChemistryAbstractThe selective hetero-dihalogenation of alkenes provides useful building blocks for a broad range of chemical applications. Unlike homo-dihalogenation, selective hetero-dihalogenation reactions, especially fluorohalogenation, are underdeveloped. Current approaches combine an electrophilic halogen source with a nucleophilic halogen source, which ...

Specific nucleophile–electrophile interactions in nucleophilic aromatic substitutions [PDF]
Organic & Biomolecular Chemistry, 2013 We herein report results obtained from an integrated experimental and theoretical study on aromatic nucleophilic substitution (S(N)Ar) reactions of a series of amines towards 1-fluoro-2,4-dinitrobenzene in water. Specific nucleophile-electrophile interactions in the title reactions have been kinetically evaluated.

Multicomponent Molecular Editing of Polybutadiene: From Design Space to Battery Function. [PDF]
Adv Sci (Weinh)Multicomponent molecular editing transforms polybutadiene into an 18‐member polymer library with tunable thermal properties, nanoscale organization, and molecular dynamics. Mapping this multidimensional design space reveals distinct molecular input–property relationships and guides the selection of a candidate electrolyte additive for lithium–sulfur ...

Handicap-Recover Evolution Leads to a Chemically Versatile, Nucleophile-Permissive Protease. [PDF]
, 2015 Mutation of the tobacco etch virus (TEV) protease nucleophile from cysteine to serine causes an approximately ∼104 -fold loss in activity. Ten rounds of directed evolution of the mutant, TEVSer , overcame the detrimental effects of nucleophile exchange ...
