Photoinduced Cleavage of Alkenyl Fluorides for Nucleophilic Acyl Substitution via In Situ Generated Acyl Fluorides. [PDF]

open access: yesOrg Lett
Acyl fluorides are valuable intermediates due to their stability and unique reactivity with amines, enabling selective acyl substitution. We report a mild, one-pot method to access amides, esters, and thioesters from alkenyl fluorides. Visible-light photoexcitation of 4-nitrophthalonitrile promotes cleavage of the alkenyl fluoride, forming acyl ...

Palladium-Catalyzed Decarbonylative Alkylation of Acyl Fluorides [PDF]

open access: yesOrganic Letters, 2020
Palladium-catalyzed decarbonylative alkylation reactions of acyl fluorides have been developed using alkylboranes having β-hydrogens. A wide range of functional groups were well tolerated, even at the high temperature required for decarbonylation. This protocol provides a diverse C(sp2)-C(sp3) bond formation via a highly efficient decarbonylative ...

Functionalized porphyrins from meso-poly-halogeno-alkyl-dipyrromethanes: synthesis and characterization

open access: yesComptes Rendus. Chimie, 2021
Starting from pyrrole-carbinol derivatives, a set of three optimized experimental conditions was used to prepare six dipyrromethanes (DPM) bearing meso-poly-halogeno-alkyl chains. On the one hand, the condensation of $p$-anisaldehyde and the DPMs bearing
