By taking into consideration bent bonds (τ-bonds, tau-bonds), the antiperiplanar hypothesis, the classic theory of resonance, and the preference for staggered bonds over eclipsed bonds in tetrahedral systems, a simple qualitative model is presented to rationalize the conformation and reactivity for a wide range of compounds containing double bonds and/or carbonyl groups. Alkenes, carbonyl and carboxyl derivatives, conjugated systems as well as other functional groups are revisited. This also leads to a simple model to understand aromaticity, and electrocyclic reactions. The bent bond model and the antiperiplanar hypothesis provide a qualitative model for better understanding the electron delocalization and the reactivity inherent to unsaturated organic systems by an alternative view of the classic resonance theory. © 2011 The Royal Society of Chemistry.

The synthesis of N,N-disubstituted aminodifluorosulfinium tetrafluoroborate salts is reported, and their behavior as deoxofluorinating agent was evaluated. The deoxofluorination reactions were performed using a primary alcohol, a secondary alcohol and a ketone. Results show that subtle modification of the structure of the reagents can noticeably affect the reactivity and the selectivity in deoxofluorination reactions. © 2013 Elsevier B.V.
