A new method for the synthesis of metal complexes with thiolate coordinatio
n is described which eliminates the need for protection/deprotection of the
thiol. The reaction in methanol of 2,2'-dithiodibenzaldehyde with nickel(I
I) complexes containing coordinated primary amines results in the concomita
nt Schiff-base condensation and cleavage of the disulfide bond to form a ch
elating amine/thiolate ligand. This method is used to synthesize nickel(II)
complexes with varying N/S donor sets, including the first structurally ch
aracterized nickel complexes of tetradentate N3S ligands. [Ni(C11H16N3S)]BP
