Recently, Preti and co-workers (291) prepared Co(II) complexes with piperidine (pipdtc), thiomorpholine (Timdtc), and iV-methylpiperazine-4-carbodithioate (Me-Pzdtc) (XX). 

The two major methods used for the synthesis of cobalt(III) dithiocar-bamates are (a) treatment of a cobaltous salt with aqueous NaR2dtc in the presence of air, or (b) oxidation of a cobalt(II) salt with tetraalkyl-dithiuram disulfides. In recent years, a complex with morpholine-4-carbodithioate (Mdtc), [CofMdtcla], has been prepared and character-... 

S-methyldithiocarbazate. The reaction sequence (2) starts with the ketone and hydrazine carbodithioate. A third synthetic method, Eq. (3), which has proven most useful for attaching a heterocyclic ring at on the thiosemiearbazone moiety [111], is shown below ...

A comparative study of the electronic structures of A,A-diethyldithiocarbamate and pyrrole-A-carbodithioate has been undertaken.961 The enthalpy of formation of [Ni(S2CNMe2)2] (—146.1 10.9 kJmol-1) has been measured.962 The square planar dithiocarbamate complexes can be oxidized to the corresponding five-coordinate Ni111 dithiocarbamate complexes [Ni(S2CNR2)2X] (X = I, Br, C104) using Br2, I2, or (N0)C104.963,964... 

VOSO4 reacts with morpholine-4-carbodithioate [mdtc (4)] (1 2) in aqueous solution, pH 4, to form a dull-brown compound which is unstable and slowly... 

S-Methyl-A-(2-pyridyl)methylenedithiocarbazate (nns) can be prepared by the condensation of S-methyldithiocarbazate and pyridine-2-aldehyde. The low-spin complexes [Fe(nns)2].X (X = CIO or FeCl ) have both been isolated.2,1.3-Benzothiodiazole. 2,1,3-benzoselenodiazole, and their derivatives (L) form the octahedral complexes FeL2Cl3. and morpholine-4-carbodithioate (mdtc) forms the complex [Felmdtclj]. Mossbauer and magnetic data for a series of monothio- -diketonate-iron(iii) complexes have been interpreted in terms of a thermal equilibrium between the sextet and doublet states. 

Copper(ii) complexes of isothiazole, 2,1,3-benzoselenadiazole and 2,1,3-benzothiazole, thiophenealdoxime, and morpholine-4-carbodithioate have been reported. Thiodiethanol, ethylenedithiodiacetate, and diethylene-trithiodiacetate all form 1 1 complexes with...

Oxidation of the chloromethyloxadiazole (44c) with sulfur and triethylamine in dimethyl-formamide below 50 °C gave the salt (44d) which formed a carbodithioate (44e) 533 nm) on... 

The interesting ligand (l)136 has two potential chelating modes upon ionization. Depending on its tautomeric state, either N,S or S,S coordination allows it to act as a bidentate chelating ligand. Apparently, it acts as a 2-aminocyclopent-l-ene-l-carbodithioate, i.e. as a 1,1-dithiolate, to form Mo02L2 complexes.136... 

Aryl- and 5-heteroaryl-l,2,3,4-thiatriazoles 9 are quite stable and can also be prepared by the reaction of aromatic (respectively heteroaromatic) carbodithioates <1961ACS1104> or A-thioacyl dithiophosphates 141 <2002J(Pl)1271> with sodium azide (Equation 12). 

This method is not general and only a limited number of 5-alkyl-l,2,3,4-thiatriazoles were prepared by this reaction. Ikeda and co-workers have described a convenient method for the synthesis of both 5-alkyl- and 5-aryl-l,2,3,4-thiatriazoles 9 by reaction of l-methyl-2-thioacylpyridinium salts 143 with sodium azide (Scheme 33). Compound 143 can be prepared from pyridium salt 142 by reaction with dithiocarboxylic acid derivatives. The synthesis can conveniently be carried out as a one-pot reaction from 2-chloro-l-pyridinium salt 142 and carbodithioate leading to final compounds 9 in high yields. The 5-alkyl-l,2,3,4-thiatriazoles 9 were isolated as oils <1990S415, 1990ZC67>.
