Urushibara Co catalysts can be prepared exactly in the same way as the corresponding Ni catalysts, using cobalt chloride hexahydrate instead of nickel chloride hexahydrate as starting material. Similarly as with Raney catalysts, Urushibara Co has been found to be more effective and selective than Urushibara Ni in the hydrogenation of nitriles, affording high yields of primary amines.105,106... 

A mixture of 1.5 1. of water, 240 g. (1.0 mole) of sodium sulfide nonahydrate, and 64 g. (2.0 gram atoms) of sulfur is stirred until the sulfur dissolves. After filtration the solution is added (10-15 minutes) with stirring to a solution of 242 g. (1.02 moles) of cobalt chloride hexahydrate in 1.7 1. of water. Stirring is continued for an additional...

Fisher found that cobaltous chloride hexahydrate significantly inhibits the formation of exudate in the rat granuloma-pouch technique. A subcutaneous dose of the compound, equivalent to 2 mg of elemental cobalt/kg/ day produces approximately the same effect as 2 mg/kg/day of subcutaneous hydrocortisone. However, when injected into adrenalectomized rats, there is no significant reduction of granuloma formation. 

Preparation of polymers from dithiooxamide 22 In a three-necked 100 mL flask, equipped with a reflux condenser and a glass inlet tube, a mixture of cobalt chloride hexahydrate (2.38 g, 0.01 mol) in 20 mL ethanol and dithiooxamide 22 (1.2 g, 0.01 mol) in 20 mL ethanol and 5 mL DMSO were added and stirred at 70-80 °C, under a thin stream of nitrogen gas, for 24 h. At the end of the reaction, the mixture was poured into 300 mL of distilled water. The dark powdery precipitated polymer complex was filtered by suction in a Buchner funnel, washed thoroughly five times with hot distilled water, twiee with diethyl ether and then dried under vacuum at 40 °C for 24 h. The light-brown polymerie eobalt complexes were obtained in a yield of 87%. IR (KBr) -1300-1390 (C-N), -1080-1170 (C=S) cm". ... 

Propyne added at -40° to a mixture of excess acetonitrile and cobaltous chloride hexahydrate, then NaBH4 added with stirring, the cooling bath removed, the temp, allowed to rise to -20°, after 20 min. transferred at -30° to an evacuated steel autoclave, heated during ca. 30 min. to 80°, and the products isolated when the pressure has decreased from 7 to 1 atm. during 4 hrs. 2,4,6-trimethyl pyridine...

Okamoto and coworkers reported a cobalt-catalyzed cycloaddition reaction of nitriles and a,cycloaddition reaction from the corresponding substrates with excellent regioselectivity (Scheme 3.10). More specifically, symmetrical and unsymmetrical 1,6-diynes and 2-cyanopyridine reacted in the presence of 5 mol% of dppe, 5 mol% of... 

A similar synthesis incorporating cobalt chloride hexahydrate (C0CI2 6H2O) and PEI produced a reddish-yeUow composite solution that was shown to be composed of hexagonal nanoflakes that were less than 100nm in size. Both, FETEM and...
