In general, the complexes are prepared by mixing aqueous or alcoholic solutions of the sodium, ammonium or potassium salt of the ligand and CrCl3-6H20, sometimes with Zn dust present.997,998 However, in some cases anhydrous conditions are necessary to prevent the formation of polymeric hydrolysis products,986 and dithiophosphate is much more resistant to temperature and extremes of pH than dithiocarbamate or xanthate. In the preparation of L3, where L is 4-aminophenazonedithiocarbamate, aqueous Cr(N03)3 was added to the reaction mixture from the preparation of the ligand.999...

Salts of the ester 0,0 -diethyl dithiophosphate have been prepared by two different methods. One involves the reaction of (C2H50)2P(S)C1 with potassium hydrogen sulfide.1 The other is the reaction of phosphorus (V) sulfide with ethanol followed by the addition of metal halide.1-3 The second method is the basis for this preparation, although the chromium(III) compound has not previously been reported. Salts of cobalt(III), nickel(II), and lead(II) can be prepared by analogous reactions using cobalt (III) fluoride, nickel(II) chloride 6-hydrate, and lead(I) oxide, respectively. 

Orthotelluric acid, l,3-dihydrobenzo[c]tellurophene 1,1-diiodide, potassium O,O-dialkyl dithiophosphate, and triethylamine in dichloromethane were stirred for two hours. The resulting solution was poured into water to precipitate a white solid that was proven by X-ray crystallographic analysis to be an orthotellluric acid derivative4. 

Phenyl tellurium Bis[diethyldithiocarbamate] 0,0-Diethyl Dithiophosphate2 To a solution of 1.91 g (4.0 mmol) of phenyl tellurium bisfdiethyldithiocarbamate] chloride in dichloromethane are added 0.90 g (4.0 mmol) of potassium 0,0-dielhyl dithiophosphate. The mixture is stirred for 2 h and then filtered. The filtrate is taken to dryness. The yellow residue is recrystallized from dichloromethane/hexane by slow evaporation m.p. 149-151° (dec.). 

Diorgano tellurium dichlorides reacted with ammonium 0,0 -dialkyl dithiophosphates in refluxing carbon disulfide4 or with potassium O.O -dialkyl dithiophosphates3 in toluene to give diaryl tellurium bis[O,0 -dialkyl dithiophosphates] as air-stable yellow or colorless solids. 

When the potassium salts of thiolacetic acid or 0,0-diethyldithiophosphoric acid are used, the 3-0-acetate or 3-0,0-diethyldithiophosphate derivative is obtained. Thioepichlorohydrin was believed to be an intermediate, and, in fact, treatment of thioepichlorohydrin with the above-mentioned salts in aqueous media gives similar results. In absolute ethanol or in 1-propanol, the reaction with the dithiophosphate salt gives mainly the thiirane derivative 38 instead of the thietane, 37. Reactions of thioepichlorohydrin with oxygen nucleophiles (H20, 172,178,179a, 179b phCOj, ClCHjCOa, CH2=C(R)C02, ... 

The formation of desaurins from ketones, carbon disulfide, and base 1275,1281,1282,1285-1290 believed to involve nucleophilic attack on a thioketene by the dianion of a 1,1-dimercaptoalkene, as shown for the synthesis of 572. Related syntheses involve the use of thiophosgene instead of carbon disulfide and the use of diazoalkanes or phosphonium and sulfonium ylides instead of a ketone and base. Treatment of perfluoroiso-butylene with fluoride ion and elemental sulfur in a dipolar, aprotic solvent ° °° or with sources of anionic sulfur (potassium sulfide, sodium hydrosulfide,potassium thiocyanate,sodium thiosulfate, dithiocarbamate salts, dithiophosphate salts ) give the dimer (573) of bis(trifIuoromethyl)-thioketene. Similarly, other 2,4-bis(methylene)-l,4-dithietanes are obtained by treating 2,2-dichlorovinyl ketones with anionic sulfur re-...
