Insights into Ag(i)-catalyzed addition reactions of amino alcohols to electron-deficient olefins: competing mechanisms, role of catalyst, and origin of chemoselectivity

Abstract

The origin of the chemoselectivities of Ag(i)-catalyzed addition reactions of amino alcohols to olefin has been predicted for the first time.

Activation Pathway of C‐H and C–C Bonds of Ethane by Pd Atom with CO2 as a Soft Oxidant

“…6‐311G(d) basis set for C, O, H atoms and the Los Alamos National Laboratory basis set of double‐ξquality(LANL2DZ) was used for Pd atom. Gaussian 09 has been widely used to clarify the detailed mechanisms of transition metal‐catalyzed and organic catalytic reactions . The convergence criteria using the default values of the Gaussian 09 program.…”

Design and Assembly of a Hierarchically Micro- and Mesoporous MOF as a Highly Efficient Heterogeneous Catalyst for Knoevenagel Condensation Reaction

“…Rare-earth (RE) hexanuclears have been reported by Prof. Mohamed Eddaoudi to illustrate the availability of such RE hexanuclears for constructing stable MOFs. , Among all application fields, heterogeneous catalysis is a significantly vital and useful research hotspot for MOFs. Compared with homogeneous catalysts, , heterogeneous catalysts have been widely used in many fields due to size-selectivity, recyclability, and ease of purification. − The catalysis efficiency can be remarkably accelerated by mesoporous MOFs, because mesoporous structures can directly facilitate the diffusion of substrates and products. Knoevenagel condensation reaction, as a common organic reaction, is an effective means to synthesize ponderable C–C coupling intermediate chemicals, which can be conventionally catalyzed by Lewis basic homogeneous catalysts .…”
