Novel processes for preparing poly(pentafluorosulfanyl)aromatic compounds are disclosed. Processes include reacting an aryl sulfur compound with a halogen and a fluoro salt to form a poly(halotetrafluorosulfanyl)aromatic compound. The poly(halotetrafluorosulfanyl)aromatic compound is reacted with a fluoride source to form a target poly(pentafluorosulfanyl)aromatic compound.
A method for producing a biaryl compound, comprising reacting an aromatic organic compound with at least one compound selected from the group consisting of aromatic organoboron compounds and boroxine compounds, in the presence of a zero-valent nickel catalyst, phosphine ligand and base.

A process for achieving nucleophilic substitution upon an unactivated monocyclic or polycyclic aromatic or heteroaromatic substrate bearing a suitable leaving group comprising the substitution of said leaving group by an anionic nucleophile is catalyzed with a cyclic or acyclic polydentate chelating ligand, e.g. a crown ether or a cyclic polyether. The process is applicable, inter alia, as the first step in the preparation of ortho-substituted benzenesulfonyl chloride derivatives, or ortho-benzenedithiol, from ortho-dichlorobenzene.
