Arenesids

Arenesids is a term that does not have a widely accepted, standardized definition in mainstream chemistry. In the limited literature where it appears, arenesids are described as arene-derived ligands that include a sulfur-containing substituent capable of coordinating to metal centers. The coinage reflects a combination of the arene core with a sulfur-based link, but there is no consensus on a formal class or nomenclature.

In proposed conceptions, an arenesid comprises an arene ring bearing a pendant sulfur donor, such as a thioether or related sulfur-containing group, which can bind to transition metals to form metal–sulfur–aryl linkages. The arene framework is sometimes suggested to participate in the overall electronic landscape of the complex, but detailed, reproducible structural characterizations are scarce, and many descriptions remain hypothetical.

Historically, the term appears sporadically in speculative discussions or niche notes rather than in comprehensive reviews or authoritative databases. It is not recognized by major chemical nomenclature authorities, and it has not become part of standard ligand design language in organometallic chemistry.

Synthesis and examples of arenesids are not widely documented. Any claimed motifs would be part of bespoke ligand design efforts in specific studies, with details tightly linked to the particular metal center and reaction context. Consequently, there is no substantial body of experimental data outlining general synthetic routes, reactivity patterns, or established applications for arenesids.
