Dithiocarbamate S- l-

Aminocyclopentene-l-dithiocarbamic acid (LH) forms a series of complexes, MIjCM = Ni", Co", or Cu"), in which the ligands are S,S-bonded (427). Diethanoldithiocarbamic acid forms Cu[(HOC2H4)2-NCS2]2, which is a monomeric, planar, CUS4 chromophore in solution, but Cu - S interaction probably occurs between neighboring molecules in the solid state (428). 

The synthesis and characterization of [Ir(S2P(Me2-C6H3-2,4)2)3] and [Ir(S2CNMeR)3], R = cyclohexyl, are reported.265,266 Further tris dithiocarbamate (146) Ir111 complexes have been prepared and characterized by UV-vis spectroscopy.267 The complex [Ircp (l,2-CgFI4S2-S,S )] has been prepared and characterized by X-ray structural analysis.26... 

S-glycofuranosyl dithiocarbamates with 5-nitro-2-pyridyl 2,3,4-tri-O-benzoyl-l-thio-P-D-glucopyranoside as an acceptor gives access to valuable 1,2-ds-linked furanosyl-1-thiopyranosides [498]. Recently, Bogusiak reported that perbenzylated S-benzothiazolyl glycosides of L-arabino, D-ribo and D-xylofuranose can be used as glycosyl donors (Scheme 4.91). ... 

To increase the yields of the ring closure reactions, a new method was developed that was successfully applied for the synthesis of alicyclic fused systems of both the parent oxazolidine-2-thione and tetrahydro-1,3-oxazine-2-thione (85S1149). As an example, the synthesis of 2-thioxoperhydro-l,3-benzoxazine 103 is described. The dithiocarbamate 101, prepared from the amino alcohol 100, carbon disulfide and triethylamine, was treated with ethyl chloroformate in the presence of triethylamine, to give the thioxo derivative 103 via the transition state 102 (85S1149). In this way, the fused-skeleton thioxooxazines (91, X = S, 92) can be prepared with considerably higher yields (50-70%) than by the earlier methods (85S1149).
