Abstract

Because of its low-lying σ* orbitals, the C–S bond can interact with electron donors. In this short review, our goal is to focus on intramolecular interactions between bivalent sulfur and basic nitrogen atoms. In particular, we will consider the synthesis of selected heterobiaryls for which 1,4 N···S inter-ring interactions can be identified from X-ray diffraction data. Finally, we will briefly touch on the use of such conformational preferences in various applications.
