Origami with small molecules: exploiting the C–F bond as a conformational tool

open access: yesBeilstein Journal of Organic Chemistry
When present within an organic molecule, the C–F bond tends to align in predictable ways with neighbouring functional groups, due to stereoelectronic effects such as hyperconjugation and electrostatic attraction/repulsion.

Trifluoromethylated enaminoketones : an entry point to organofluorine chemistry

open access: yes, 1998
Two literature syntheses of trifluoromethylated enaminoketones were investigated; a Schreiber route utilising trifluoroacetic anhydride and a tertiary amine was found lacking in generality and reproducibility whilst the synthesis of 4-(ethyloxy)-1,1,1 ...
