Coordination complexes involving sydnones as ligands
Sydnones are mesioionic compounds studied for years for their versatile reactivity in substitution reactions, sydnone-alkyne or sydnone-alkene cycloaddition reactions. This perspective article focuses on the use of sydnones in coordination complexes, either through a metalation on one of the carbons of the sydnone ring, its modification to obtain polydentate ligands, or its use as a polar moiety that could influence the properties of the final complex. Such compounds are valuable either from a synthetic point of view or for their biological properties.
