  • Nickel-Catalyzed Cross-Coupling of Photoredox-Generated Radicals . . .
    As such, we propose that stereoconvergence in these processes occurs by the same Ni (III) DKR process that we have elucidated for photoredox nickel dual catalytic organoboron cross-coupling
  • Tuning the stability of organic radicals: from covalent approaches to . . .
    To stabilize an organic radical, steric protection is one of the most effective and widely used approaches It is the most direct and natural idea that steric protection can prevent the interaction of organic radicals with others, thus inhibiting their intermolecular side reactions
  • Stereoelectronic effect - Wikipedia
    Founded on a few general principles that govern how orbitals interact, the stereoelectronic effect, along with the steric effect, inductive effect, solvent effect, mesomeric effect, and aromaticity, is an important type of explanation for observed patterns of selectivity, reactivity, and stability in organic chemistry
  • The subtle art of radical control - ScienceDirect
    More broadly, stereocontrolled radical transformations remain a frontier in synthesis, challenged by the generally low reaction barriers associated with radical reactions
  • Doubly stereoconvergent crystallization enabled by asymmetric catalysis
    We were interested in testing the notion that by leveraging epimerization to achieve stereoconvergence in complex systems, we could accrue unique advantages through the merged application of asymmetric catalysis and crystallization-driven selectivity
  • 3: Conformations and Stereochemistry - Chemistry LibreTexts
    Before we begin our exploration of stereochemistry and chirality, we first need to consider the subject of conformational isomerism, which has to do with rotation about single bonds
  • ja513079r 1. - ACS Publications
    Stereoconvergence then results via stereochemical scrambling of the secondary alkyl subunit through dissociation and recombination
  • Stereoretentive radical-based alkyl-alkyl cross-coupling
    In this work, we report a scalable stereoretentive radical-radical cross-coupling of two distinct, transient alkyl radicals, derived from enantioenriched sulfonylhydrazides and achiral primary and secondary alkyl halides, achieved without chiral ligands, directing groups, or exogenous redox agents
  • ‘Absurd’ radical reaction keeps stereochemistry intact
    According to organic chemistry dogma, if you generate a radical on a chiral carbon, it’s going to lose its stereochemistry and racemize But a new cross-coupling reaction that forges bonds between radicals on two sp 3 carbons retains the stereochemistry of one of the coupling partners
