Paradigms and paradoxes : systematics in the study of the simplest sulfenic acids and sulfoxides, and a comparison between sulfur–oxygen and nitrogen–oxygen bonds

Some particularities in the bonding of simple sulfenic acids and their sulfoxide isomers are explored using accurate theoretical methods. Some unexpected results are described using thermochemical results on diverse nitrogen– and/or oxygen– containing functionalities such as amino, nitro, nitroso and nitrite derivatives.
