Journal ArticleDOI
Chromatographic hydrophobic parameters in correlation analysis of structure-activity relationships.
TL;DR: It is suggested that the chromatographically obtained RM and delta RM parameters could find a wider applicability in structure-activity relationships, and that their use would result in improved correlation of data.
Journal ArticleDOI
Base-Promoted Protodeboronation of 2,6-Disubstituted Arylboronic Acids
TL;DR: Results provide fundamental insight into deboronative mechanisms with implications for cross-coupling reactions, regioselective deuteration/tritiation for isotopic labeling, and the design of new (18)F-trifluoroborate radioprosthetics.
Book ChapterDOI
Electrophilic Substitutions of Five-Membered Rings
TL;DR: In this article, the authors provide a sufficiently complete summary of all the quantitative and semiquantitative information available concerning electrophilic substitution in five-membered heteroaromatic rings.
Journal ArticleDOI
Developing a Modern Approach To Account for Steric Effects in Hammett-Type Correlations.
TL;DR: The effects of aryl ring ortho-, meta-, and para-substitution on site selectivity and enantioselectivity were investigated in reactions and it was demonstrated that the electronic and steric effects of various substituents on selectivities obtained in these reactions can be described by NBO charges, the IR carbonyl stretching frequency, and Sterimol values of various substituted benzoic acids.
Book ChapterDOI
The Hammett Equation—the Present Position
TL;DR: This chapter represents—in a certain sense—the introduction to the whole book, since the Hammett equation is the oldest and most developed empirical relationship, and many general features can be demonstrated by using it as the only available example.
