Trapping of a thiolate-->dibromine charge-transfer adduct by a macrocyclic dinickel complex and its conversion into an arenesulfenyl bromide derivative.
Stuck on sulfur: The first transition-metal complexes with S-Br units are surprisingly stable. Solid 3 is stable for at least six months and under vacuum solid 2 does not lose Br(2). The formation of the first structurally characterized transition-metal arenesulfenyl bromide complex 3 occurs with a change of the spin ground state from S = 2 to S = 0.
