A simple and efficient approach of C-S cross-coupling of a wide variety of (hetero)aryl thiols and (hetero)aryl halides under mild conditions, mostly at room temperature, catalyzed by well-defined singlet diradical Ni(II) catalysts bearing redox noninnocent ligands is reported. Taking advantage of ligand centered redox events, the high-energetic Ni(0)/Ni(II) or Ni(I)/Ni(III) redox steps were avoided in the catalytic cycle. The cooperative participation of both nickel and the coordinated ligands during oxidative addition/reductive elimination steps allowed us to perform the catalytic reactions under mild conditions.

We provide herein a mechanistic analysis of aryl sulfoxide excited state processes, inspired by our recent report of aryl sulfoxide based fluorescent chemosensors. The use of aryl sulfoxides as reporting elements in chemosensor development is a significan

Metal-free C-H thioarylation of arenes and heteroarenes using methyl sulfoxides constitutes a general protocol for the synthesis of high value diaryl sulfides. The coupling of arenes and heteroarenes with in situ activated sulfoxides is regioselective, uses readily available starting materials, is operationally simple, and tolerates a wide range of functional groups.
Sulfoxides as response elements for fluorescent chemosensors

Sulfoxides are shown to be viable reporting groups for fluorescent chemosensor development. Metal coordination of sulfoxide-appended fluorophores suppresses excited-state pyramidal inversion of the sulfoxide, leading to enhanced fluorescence emission. This new structural motif allows the construction of fluorescent chemosensors that do not require nitrogen coordination as part of the signaling process, that have a range of selectivities and affinities for oxophilic metal ions, and that can function in water.
