A DFT Study on FeI/FeII/FeIII Mechanism of the Cross-Coupling between Haloalkane and Aryl Grignard Reagent Catalyzed by Iron-SciOPP Complexes

open access: yesMolecules, 2020
To explore plausible reaction pathways of the cross-coupling reaction between a haloalkane and an aryl metal reagent catalyzed by an iron–phosphine complex, we examine the reaction of FeBrPh(SciOPP) 1 and bromocycloheptane employing density functional ...

Aminocatalytic stereoselective synthesis of (E)-α-naphthyl enals via cross-coupling-like reaction of 1-bromo-2-naphthols with enals

open access: yesGreen Synthesis and Catalysis, 2021
A diphenyl prolinol TMS ether-catalyzed stereoselective reaction of 1-bromo-2-naphthols with enals has been developed. The organocatalyzed cross coupling-like reaction servers an efficient approach to sterically congested (E)-α-naphthyl enals. The formal

Cross-Coupling Reaction with Lithium Methyltriolborate

open access: yesMolecules, 2012
We newly developed lithium methyltriolborate as an air-stable white solid that is convenient to handle. The good performance of this triolborate for metal-catalyzed bond-forming reactions was demonstrated in palladium-catalyzed cross-coupling reactions ...

Vinyl Esters and Vinyl Sulfonates as Green Alternatives to Vinyl Bromide for the Synthesis of Monosubstituted Alkenes via Transition-Metal-Catalyzed Reactions

open access: yesChemistry, 2023
This review summarizes the applications of vinyl sulfonate and vinyl acetate as green alternatives for vinyl bromide in cross-coupling reactions. In the first part, the preparation of vinyl sulfonates and their cross-coupling reactions are briefly ...

Mechanistic Implications for the Ni(I)-Catalyzed Kumada Cross-Coupling Reaction

open access: yesInorganics, 2017
Herein we report on the cross-coupling reaction of phenylmagnesium bromide with aryl halides using the well-defined tetrahedral Ni(I) complex, [(Triphos)NiICl] (Triphos = 1,1,1-tris(diphenylphosphinomethyl)ethane).

Research progress of supported palladium catalysts for Suzuki cross-coupling reaction of aryl chlorides

open access: yes上海师范大学学报. 自然科学版, 2020
The palladium(Pd)-catalyzed cross-coupling reaction between organic boricacids and aryl halides provides a powerful and general method for the formation of carbon-carbon bonds known as the Suzuki cross-coupling.It was found that with the cheap and ...

The role of the N*(1535) resonance and the pi^- p --> KY amplitudes in the OZI forbidden pi N --> phi N reaction [PDF]

open access: yes, 2008
We study the pi N --> phi N reaction close to the phi N threshold within the chiral unitary approach, by combining the pi^- p --> K^+ Sigma^-, pi^- p --> K^0 Sigma^0 and pi^- p --> K^0 Lambda amplitudes with the coupling of the phi to the K components of
