Air and moisture stable diaryl dithiocarbamate salts, Ar2NCS2Li, result from addition of CS2 to Ar2NLi, the latter being formed upon deprotonation of diarylamines by nBuLi. Oxidation with K3[Fe(CN)6] affords the analogous thiuram disulfides, (Ar2NCS2)2, two examples of which (Ar = p-C6H4X; X = Me, OMe) have been crystallographically characterised. The interconversion of dithiocarbamate and thiuram disulfides has also been probed electrochemically and compared with that established for the widely-utilised diethyl system. While oxidation reactions are generally clean and high yielding, for Ph(2-naphthyl)NCS2Li an ortho-cyclisation product, 3-phenylnaphtho[2,1-d]thiazole-2(3H)-thione, is also formed, resulting from a competitive intramolecular free-radical cyclisation. To demonstrate the coordinating ability of diaryl dithiocarbamates, a small series of Co(III) complexes have been prepared, with two examples, [Co{S2CN(p-tolyl)2}3] and [Co{S2CNPh(m-tolyl)}3] being crystallographically characterised. Solvothermal decomposition of [Co{S2CN(p-tolyl)2}3] in oleylamine generates phase pure CoS2 nanospheres in an unexpected phase-selective manner.
