A quantitative approach to polar organic reactivity$

A method is presented which allows one to predict toxic effects which are triggered by the formation of covalent bonds between electron-deficient (electrophilic) compounds and biological

A Lewis basicity scale in dichloromethane for amines and common nonprotogenic solvents using a zinc(II) Schiff-base complex as reference Lewis acid.

Lewis basicity is governed by the steric hindrance at the donor atom and involves very different relative basicities than those predicted considering typical reference Lewis acids, given the sterically encumbered nature of commonly involved Lewis acidic organometallic complexes.

Transfer of a positively charged acyl group between substituted phenolate ion nucleophiles: the brønsted β for the calibrating equilibrium for N-methylisonicotinyl (4-carbonyl-N-methylpyridinium) transfer

A new method is demonstrated for determining βeq for group transfer from 4-nitrophenyl esters; it employs the rate constant for the reaction of 2,6-difluorophenolate ion with substituted phenyl ester as a surrogate for the reactivity of the 4-Nitrophenolate ion and yields βeq= 1.55 for the N-methylisonicotinyl transfer reaction.

Application of the methylenology principle to substitution reactions. A theoretical study

The substitution reaction of chloride with methyl chloride, 2-chloroethyl radical and allyl chloride has been investigated with a number of different ab initio theoretical methods. Depending on the

Catalyst-free, aza-Michael polymerization of hydrazides: polymerizability, kinetics, and mechanistic origin of an α-effect.

Overall, the difference in reactivity between hydrazides and amines is attributed to the adjacent nitrogen atom in hydrazide that acts as an efficient hydrogen-bond donor that facilitates intramolecular proton-transfer following the formation of the zwitterion intermediate.

Scaling Relations for Acidity and Reactivity of Zeolites

This work computationally investigated how catalytic reactivity scales with acidity for a range of zeolites with different topologies and chemical compositions and found that straightforward correlations are limited to zeolite with the same topology.

Azomethane Decomposition Catalyzed by Pt(111): An Example of Anti-Brönsted−Evans−Polanyi Behavior

The molecular mechanism of azomethane decomposition on a clean Pt(111) surface has been studied by means of a periodic density functional theory (DFT) approach. Three main elementary steps have been

Intra- and intermolecular reaction selectivities of γ-substituted adamantanylidenes.

A study of adamantanylidenes having a γ-substituent (R) was undertaken to gauge how inductive and steric effects of remotely positioned functional groups influence intra- and intermolecular product

Rational Optimization of Lewis-Acid Catalysts for the Direct Amination of Alcohols, Part 1 - Activity Descriptors for Metal Triflates and Triflimides

Herein we report a comparison of Lewis acidity indicators (affinity scales, electronegativity, Fukui functions, global electrophilicity index) with a new in silico Beckett-Childs descriptor based on
