Fluorenyl Cations: Synthesis and Reactivity

open access: yesChemistry – A European Journal, EarlyView.
This review covers the history of fluorenyl cations from Deno's first report in 1954 on the parent fluorenyl cation to the present. The parent cation and most derivatives have only been observed as a fleeting species by mass spectrometry, UV/Vis spectroscopy, IR spectroscopy, or NMR spectroscopy while recent developments led to isolable species ...

Synthesis and Conformational Analysis of Pyran Interhalide Analogues of Galactose, Mannose, Talose, and Glucose

open access: yesChemistry – A European Journal, EarlyView.
The synthesis and conformational analysis of pyran interhalides unveiled the shortest F⋅⋅⋅I halogen bonding involving Csp3‐bound I and F atoms. Abstract There is growing interest in the preparation of multivicinal interhalide molecules. Herein, we described the synthesis of several pyran interhalide analogues of d‐galactose, d‐mannose, d‐talose, and d ...

New Click on the Block: Photocaged Hydroxylamine, an Addition to the Light‐Activatable Bioorthogonal Toolbox

open access: yesChemistry – A European Journal, EarlyView.
The retro‐Cope bioorthogonal reactivity of hydroxylamines was disabled transiently with a coumarin photolabile protecting group, which could be recovered upon removal of the protecting group by a short, 400 nm light illumination. Light‐controlled recovery of reactivity was demonstrated in bioorthogonal fluorescent labeling schemes of intracellular ...
