Journal ArticleDOI
π-Nucleophilicity in Carbon−Carbon Bond-Forming Reactions
TL;DR: In this article, a new method of parametrization was proposed that facilitates a continuous extension of the data sets without the need for reparameterization of existing data, and adjusts the N and s parameters of all presently characterized π-nucleophiles (arenes, alkenes, organometallics).
Journal ArticleDOI
Reference Scales for the Characterization of Cationic Electrophiles and Neutral Nucleophiles
Herbert Mayr,Thorsten Bug,Matthias F. Gotta,Nicole Hering,Bernhard Irrgang,Brigitte Janker,Bernhard Kempf,Robert Loos,Armin R. Ofial,Grigoriy Ya. Remennikov,Holger Schimmel +10 more
TL;DR: Mayr et al. as discussed by the authors used correlation analysis to determine the electrophilicity parameters E and N and s as defined by the equation log k(20 °C) = s(N + E).
Journal ArticleDOI
The DMAP-catalyzed acetylation of alcohols- : A mechanistic study (DMAP = 4-(dimethylamino)pyridine)
TL;DR: Both the theoretical as well as the experimental studies strongly support the nucleophilic catalysis pathway for the acetylation of tert-butylacetate.
Journal ArticleDOI
Structure-nucleophilicity relationships for enamines.
TL;DR: The kinetics of the reactions of benzhydryl cations with 22 enamines, three pyrroles, and three indoles were investigated photometrically in dichloromethane and it was shown that the nucleophilic reactivities of enamines cover more than ten orders of magnitude, comparable to enol ethers on the low reactivity end and to carbanions on the high reactsivity end.
Journal ArticleDOI
Nucleophilicities and carbon basicities of pyridines.
TL;DR: It is found that the nucleophile organocatalyst 4-(dimethylamino)pyridine (DMAP) and tertiary phosphanes have comparable nucleophilicities and carbon basicities despite widely differing Brønsted basicities.
