Carbon dioxide Cyanogen chloride

The reagent (1) also reacts with wide variety of eiectrophiies, including carbon dioxide, cyanogen, siiyi chiorides, metal halides, and phosphorus(III) chloride With methyl phenyl sulfinate, reaction of (1) leads to the formation of (phenylthio) (trimethylsiloxy)methane, a protected form of formaldehyde, by a sila-Pummerer rearrangement. ...

Cyanogen Trisulphide, (CN)2S3 or (CN)6S .—The non-volatile residue which is formed when silver cyanide acts on sulphur chloride constitutes cyanogen trisulphide. It is a dark yellow crystalline powder, insoluble in water, alcohol, ether, carbon disulphide and chloroform. It is unattacked by hydrochloric acid and is soluble in concentrated sulphuric acid. It is transformed into carbon dioxide and sulphuric acid by nitric acid or aqua regia. When distilled, the products are carbon disulphide, sulphur and tricyanuramide, N8(C3N3)3.1... 

Heated with concentrated sulphuric acid, perthioeyanic acid gives sulphur dioxide, carbon dioxide, thiourea, thiocyanic acid and ammonium sulphate. Heated with chlorine the acid gives cyanogen chloride, sulphur chloride, hydrogen chloride and a reddish-brown insoluble residue. Ferric chloride gives a coloration similar to that produced with thiocyanic acid.10... 

The formation of cyanogen chloride (CNCl) in Eq. (11) is essentially instantaneous. The second reaction in Eq. (12), the formation of cyanate, is accomplished most rapidly and completely at a pH of 10 or higher. A detention time of 30 min to 2 h is usually allowed. The cyanates can be further decomposed into nitrogen and carbon dioxide by excess chlorination, or superchlorination ... 

Nitrile synthesis. Sodium salts of carboxylic acids when heated in a sealed tube with cyanogen chloride at 200-300° are converted into the corresponding nitriles, often in high yield. Tracer studies with cyanogen bromide have shown that the carbon dioxide liberated is derived from the cyanogen halide and that the bond... 

The reaction of carbonimidoyl dichlorides with excess water results in complete hydrolysis with formation of the corresponding amine and carbon dioxide ( ). This reaction affords isocyanate as an intermediate, as evidenced by the isolation of 1,3-diphenylurea from the reaction mixture, obtained by treating phenylcarbonimidoyl dichloride with water In the reaction of tetrameric cyanogen chloride with water at 20°C 2-amino-4,6-dichloro-l,3,5-triazine (LXXXVI) is obtained, whereas at 100 C total hydrolysis to cyanuric acid (LXXXVII) occurs... 

In the presence of water, the cyanogen chloride is hydrolyzed to cyanic acid and carbon dioxide. This is a much more rapid reaction than (2). 

Olefins may be converted in high yield to a-ahtoroketones by treatment with chromyl chloride in acetone. a-Carboxyketones, generally relatively inaccessible, can be prepared by treatment of ketones with lithium 4-methyl-2,6-di-tert-butylphenoxide and carbon dioxide. Cyclic ketones result from ring expansion of methylene cycloalkanes with cyanogen azide followed by hydrolysis, a procedure which complements the standard diazo-methane-ketone approach. Functionalized cis-bicyclic ketones can be synthesized by haloketal cyclizatlon followed by hydrolysis. ...
