Azolium-2-dithiocarboxylates as redox active ligands in nickel chemistry.

ABSTRACT: The coordination chemistry of carbene-CS₂ adducts of selected NHCs and cAACs and their redox active nature in nickel complexes is reported. These azolium-2-dithiocarboxylate ligands can be considered as 1,1-isomeric dithiolene analogues bearing a 2π electron reservoir. Depending on the co-ligands attached to nickel, square planar mono- or bis-(carbene-CS₂) complexes of the types [Ni(IⁱPr)₂(carbene-CS₂)] (2a-g) (carbene = cAAC^Me, IDipp, IMes, BIMe, BIⁱPr, IⁱPr, and IⁱPr^Me) and [Ni(carbene-CS₂)₂] (3a-c) (carbene = cAAC^Me, IDipp, and IMes) are accessible by alkene substitution using [Ni(IⁱPr)₂(ƞ²-C₂H₄
