Carbon disulfide reactions with nickel

Carbon disulfide reacts with a wide range of bases to produce ligands which readily coordinate to metals. New synthetic work including the formation of aryl xanthates, disulfide products, and oxidized metal dithiolates is reviewed. The sulfur addition and abstraction reactions are discussed, along with the photobleaching reaction of [Ni(n-butyldtc)a] Bridged mercaptide complexes of nickel triad elements are also described. 

The formation of complexes of l,2,3,4-thiatriazole-5-thiol has been well described in CHEC-II(1996) 1,2,3,4-thiatriazole-5-thiol can form complexes with various metals such as palladium, nickel, platinum, cobalt, zinc, etc. <1996CHEC-II(4)691>. These complexes can be prepared either by cycloaddition reactions of carbon disulfide with metal complexes of azide anion (Equation 20) or directly from the sodium salt of l,2,3,4-thiatriazole-5-thiol with metal salts. For instance, the palladium-thiatriazole complex 179 can be obtained as shown in Equation (20) or it may be formed from palladium(ll) nitrate, triphenylphosphine, and sodium thiatriazolate-5-thiolate. It should be noted that complexes of azide ion react with carbon disulfide much faster than sodium azide itself. 

Although many transition-metal derivatives react with cyclopropenes by ring opening (See Section 2.C. and ref 107 for examples), 1,2-dimclhylcyclopropene was regenerated from the complex 8 by reaction with triphenylphosphane or carbon disulfide, and a number of related nickel ° and niobium complexes of cyclopropenes which retain the three-membered ring have been reported. ... 

Equimolar amounts of 2,3-diphenylcyclopropenone, phenyl isothiocyanate, and tetracarbonyl-nickel(O) were reacted in dimethylformamide at 65-70 C to give a mixture containing 2,3,6,8,9-pentaphenyl-l-thia-6-azaspiro[4.4]nona-2,8-diene-4,7-dione (30%). Similarly, the reaction of 2,3-diphenylcyclopropenone with carbon disulfide produced 2,3,8,9-tetraphenyl-l,6-dithia-spiro[4.4]nona-2,8-diene-4,7-dione (41 %). ... 

Hydrogenation of several 6- and 7-substituted quinoline Reissert compounds (1) in the presence of Raney nickel leads to the 2-aminomethyl-1,2,3,4-tetrahydroquinoline derivatives 68.114 A similar reduction of the Reissert compound derived from benzo[/]quinoline, followed by reaction of the crude product with carbon disulfide, gave the diazacyclopentaphenan-threne derivative 69.115... 

Sulfur may be substituted for hydrogen in the reduction of saturated hydrocarbons over nickel sulfide catalysts. In this way, carbon disulfide may be synthesized from methane plus hydrogen sulfide over nickel sulfide catalysts at 450-750°. The same reaction takes place with other hydrocarbons at slightly lower temperatures. At still lower temperatures, hydrogen sulfide adds to the double bonds of olefins in the presence of nickel sulfide, and of nickel sulfide-chromium sulfide mixtures, to yield thiols.

Shipment and. Storage, Sulfur monochloride is minimally corrosive to carbon steel and iron when dry. If it is necessary to avoid discoloration caused by iron sulfide formation or chloride stress cracking, 310 stainless steel should be used. Sulfur monochloride is shipped in tank cars, tank trucks, and steel drums. When wet, it behaves like hydrochloric acid and attacks steel, cast iron, aluminum, stainless steels, copper and copper alloys, and many nickel-based materials. Alloys of 62 Ni—28 Mo and 54 Ni—15 Cr—16 Mo are useful under these conditions. Under DOT HM-181 sulfur monochloride is classified as a Poison Inhalation Hazard (PIH) Zone B, as well as a Corrosive Material (DOT Hazard Class B). Shipment information is available (140). Uses, The reaction of S-CL with aromatic compounds can yield disulfides or mixtures of mono-, di-, and polysulfides.
