Carbohydrate Physicochemical Properties: The Innate Hydrogen Bond Donating Capacities of α‐Glucoside and α‐Galactoside Alcohol Groups

open access: yesAngewandte Chemie, Volume 138, Issue 34, 17 August 2026.
Experimental determination of the innate hydrogen bond donating capacities of the glucose and galactose non‐anomeric alcohols revealed significant variations depending on position and relative configuration, which were quantified on the pKAHY scale, relevant for MedChem purposes, hence providing another tool toward rational glycomimetic development ...

Perfluoroalkylation of aromatic systems [PDF]

open access: yes, 1997
I. We have concentrated on the synthesis of aromatic systems containing CH(_2)R(_F) groups, where R(_F) is a bulky group derived from hexafluoropropene dimer, using fluoride ion induced methodology.

Pd/C‐Catalyzed Hydrogenation of CF3‐, CF2H‐, and CF2CO2Et‐containing Pyridines: A Robust Method for Highly Functionalized containing Piperidines

open access: yesAngewandte Chemie, Volume 138, Issue 34, 17 August 2026.
A robust and efficient method to access diversely functionalized fluorinated piperidines was developed. The approach features the hydrogenation of polysubstituted pyridines bearing CF3, CF2H, and CF2CO2Et substituents using an inexpensive, readily available heterogeneous Pd/C catalyst under air‐ and moisture‐tolerant conditions, offering an appealing ...

Free-radical approaches to new fluorocarbon derivatives [PDF]

open access: yes, 1989
This thesis is concerned with the free-radical addition of nitrogen, silicon and oxygen containing compounds to fluoroalkenes and the chemistry of some of the adducts produced.

High Concentrations of Unidentified Extractable Organofluorine observed in Blubber from a Greenland Killer Whale (Orcinus orca) [PDF]

open access: yes, 2020
It is generally accepted that per- and polyfluoroalkyl substances (PFASs) occur primarily in protein-rich tissues such as blood and liver, but few studies have examined the occurrence of PFASs (in particular emerging PFASs), in lipid-rich tissues such as

Free radical reaction of fluorine containing compounds [PDF]

open access: yes, 1989
This thesis is concerned with the free-radical addition of oxygen containing compounds of the adducts produced. Free-radical additions of ether compounds to fluoroalkenes have been done by previous workers and the chemistry of some of these adducts has ...

New functionalized, differently fluorinated building-blocks via Michael addition to gamma-fluoro-alpha-nitroalkenes

open access: yes, 2006
The Michael addition of ketone-derived enamines, metalated methylene active compounds and N-methyl pyrroles to gamma-fluoro-alpha-nitroalkenes provided in moderate to good isolated yields the corresponding beta-fluoroalkyl nitro compounds, which ...
