Mechanistic insight into C−S bond construction using CO2 as a carbon source: Synthesis of benzothiazoles from 2-aminothiophenols in imidazolium acetate
Autor: Hongliang Wang, Chengbu Liu, Dongju Zhang
Publikováno v: Journal of CO2 Utilization, Vol 85, Iss , Pp 102874- (2024)
DFT calculations on synthesis of benzothiazoles via cyclization of 2-aminothiophenols with CO2 and triethoxysilane have revealed a novel mechanism that fundamentally differs from previously proposed mechanisms. In this new mechanism, the acetate anio

DFT calculations reveal the origin of controllable synthesis of β-boronyl carbonyl compounds from Cu/Pd-cocatalyzed four-component borocarbonylation of vinylarenes
Autor: Lin Liu, Yanhong Liu, Yiying Yang, Chengbu Liu, Dongju Zhang
Publikováno v: Catalysis Science & Technology. 13:2123-2133
DFT calculations show that the difference in reactivity caused by different raw materials (aryl halides/trifluoromethanesulfonate) is due to the different formation rates of intermediates in copper and palladium catalytic cycles.

Key role of a π–π complex in diaryl cross-coupling between aryldiazonium salts and arylboronic acids using photosensitizer-free gold/photoredox catalysis
Autor: Yanhong Liu, Rongxiu Zhu, Dongju Zhang, Chengbu Liu
Publikováno v: Organic Chemistry Frontiers. 9:147-155
In a new mechanism for photosensitizer-free visible-light-mediated gold-catalyzed cross-coupling, the π–π complex between aryldiazonium salts and arylboronic acids acts as a photoinitiator.

Mechanistic insight into construction of axially chiral biaryls via palladium/chiral norbornene cooperative catalysis: a DFT-based computational study
Autor: Dongju Zhang, Xuexiang Ma, Aili Feng, Chengbu Liu
Publikováno v: Catalysis Science & Technology. 12:105-115
Density functional theory calculations were performed on a prototype of three-component reactions involving aryl iodides, 2,6-substituted aryl bromides, and acrylates to understand the construction of axially chiral biaryls through the palladium/chir

DFT Mechanistic Study of IrIII/NiII-Metallaphotoredox-Catalyzed Difluoromethylation of Aryl Bromides
Autor: Xia Zhao, Jihong Xu, Yiying Yang, Dongju Zhang, Chengbu Liu
Publikováno v: Inorganic Chemistry. 60:8682-8691
The work by MacMillan et al. ( Angew. Chem., Int. Ed. 2018, 57, 12543-12548) developed an IrIII/NiII-metallaphotoredox-catalyzed difluoromethylation strategy of aryl bromides using CHF2Br as the CHF2 reagent in the presence of tris(trimethylsilyl)sil

DFT study of Ni/NHC-catalyzed C–H alkylation of fluoroarenes with alkenes to synthesize fluorotetralins: mechanism, chemoselectivity of C–H vs. C–F bond activation, and regio- and enantioselectivities of C–H bond activation
Autor: Dongju Zhang, Jihong Xu, Chengbu Liu, Xia Zhao
Publikováno v: Organic Chemistry Frontiers. 8:1520-1530
Density functional theory calculations have been carried out to elucidate the mechanism, enantio-, regio-, and chemoselectivities, and the role of the NHC ligand in the Ni/NHC-catalyzed alkylation of fluoroarenes with alkenes, a new strategy that exc

Mechanistic Insight into Palladium-Catalyzed γ-C(sp3)–H Arylation of Alkylamines with 2-Iodobenzoic Acid: Role of the o-Carboxylate Group
Autor: Dongju Zhang, Xuexiang Ma, Zhe Han, Chengbu Liu
Publikováno v: Inorganic Chemistry. 59:18295-18304
Density functional theory calculations were performed to understand the distinctly different reactivities of o-carboxylate-substituted aryl halides and pristine aryl halides toward the PdII-catalyzed γ-C(sp3)-H arylation of secondary alkylamines. It
