Formation, Characterization, and Reactivity of Acyl Palladium Complexes in Pd(OAc)2/PCy3‑Catalyzed Transformation of Acyl Fluorides

open access: yes, 2022
The formation of benzoyl­(benzoato)palladium complexes via a stoichiometric reaction between benzoyl fluorides, Pd­(OAc)2, a hydrosilane and a phosphine is reported. NMR studies of the acyl palladium complex reveal the generation mechanism of the complex

Deoxyfluorination of Carboxylic Acids with CpFluor: Access to Acyl Fluorides and Amides

open access: yesOrganic Letters, 2021
3,3-Difluoro-1,2-diphenylcyclopropene (CpFluor), a bench-stable fluorination reagent, has been developed in the deoxyfluorination of carboxylic acids to afford various acyl fluorides. This all-carbon-based fluorination reagent enabled the efficient transformation of (hetero)aryl, alkyl, alkenyl, and alkynyl carboxylic acids to the corresponding acyl ...

Three-Component Coupling of Acyl Fluorides, Silyl Enol Ethers, and Alkynes by P(III)/P(V) Catalysis

open access: yes, 2021
Catalysis by late transition metal complexes is enabled by their facile reversible redox reactivity based on their partially filled d-orbitals. The realization of such redox catalysis by p-block elements is a challenging but rewarding research subject ...

)‐diones via C−H Alkylation/Cyclization with α,β‐Unsaturated Acyl Fluorides [PDF]

open access: yes, 2023
Transition-metal-catalyzed directed C-H functionalization reactions are a powerful method to construct N-heterocycles. However, compared to the formation of five- and six-membered rings, that of seven-membered rings has been much less explored. Here, the

Cationic Rhodium(I) Tetrafluoroborate-Catalyzed         Intramolecular Carbofluorination of Alkenes           via the Activation of a Carbon–Fluorine Bond in Acyl Fluorides

open access: yes, 2022
C–F bonds of acyl fluorides can be cleaved and added across teth-ered alkenes in the presence of a cationic rhodium(I) tetrafluorobo-rate catalyst. This 1,2-carbofluorination reaction offers a powerful method for the synthesis of tertiary alkyl fluoride ...

An Improved Protocol for the Stereoselective Synthesis of β‑d‑Glycosyl Fluorides from 2‑O‑Acyl Thioglycosides

open access: yes, 2022
A safe and operationally simple protocol for the preparation of β-d-glycosyl fluorides is presented. We demonstrate that a precise combination of XtalFluor-M, N-bromosuccinimide, and Et3N·3HF can mediate facile, high-yielding, and diastereoselective ...

Electrophilic N-Trifluoromethylthiophthalimide as a Fluorinated Reagent in the Synthesis of Acyl Fluorides

open access: yes, 2021
Herein we report the deoxygenated fluorination of readily available carboxylic acids. A series of acyl fluorides have been synthesized using shelf-stable N-trifluoromethylthiophthalimide as a fluorinated reagent for the first time. Scale-up reactions and

Exogenous Ligand-Free NiH-Catalyzed Hydroacylation of Aryl Alkenes with Aroyl Fluorides

open access: yes, 2022
Acyl fluorides have emerged as efficient acyl group donors, but these attractive reagents have rarely been utilized in transition-metal-catalyzed hydroacylation.
