Nitro syl chloride

Other methods (which are either more tedious or more expensive) include the reaction of nitric acid with SO2 or P4O10 and the reaction of nitro-syl chloride with AgN03 ... 

Other processes for making chlorine include sodium manufacture, caustic potash manufacture, hydrogen chloride decomposition, the nitro-syl chloride (NOC1) process, and a process where salt is treated with nitric acid to form sodium nitrate and chlorine with nitrosyl chloride (containing 4 to 10% nitrogen tetroxide) as a by-product. The nitrosyl chloride vapor is placed in contact with oxygen to produce nitrogen tetroxide and chlorine ... 

Indirect replacement of the a-hydrogen atom of carboxylic esters by the nitroso group is remarkable. This procedure uses ketene 0-alkyl O -silyl acetals (1), generated from carboxylic esters, which are treated with nitric oxide or isopentyl nitrite in the presence of titanium(IV) chloride. In the absence of an a-hydrogen a-nitroso esters (2) are obtained. a-Nitroso esters with an a-hydrogen undergo isomerization to oximes of a-keto esters (3 equation 1). Similarly, silyl enol ethers of aldehydes or ketones can be used instead of the carbonyl compound itself for nitrosation. Thus, treatment of enol ether (4) with nitro-syl chloride gives the a-nitroso aldehyde (5 equation 2), which is quite stable at 0 C, but dimerizes at room temperature. 

Tetraphenylporphinesulfonate (TPPS), 5,10,15,20-Tetrakis (4-sulfonatophenyl) porphyrinato Iron111 Chloride (FeTPPS), and 5,10,15,20-Tetrakis (4-sulfonatophenyl) porphyrinato Iron111 nitro-syl Chloride (FeNOTPPS) were investigated as candidate compounds for inhibition of acetylcholinesterase of Drosophila melanojyaster [166]. 

Examples 1-11 illustrate some mild methods that can be used to cleave amides. Equations 1 and 2 indicate the conditions that were used by Woodward and Eschenmoser, respectively, in their synthesis of vitamin B12. Butyl nitrite, nitro-syl chloride, and nitrosonium tetrafluoroborate (NO BF4 ) have also been used to cleave amides. Since only tertiary amides are cleaved by potassium f-butoxide (eq. 3), this method can be used to effect selective cleavage of tertiary amides in the presence of primary or secondary amides. (Esters, however, are cleaved by similar conditions.) Photolytic cleavage of nitro amides (eq. 4) is discussed in a... 

Nitric acid converts osmium to volatde osmium tetroxide but forms a nitro-syl complex with ruthenium that remains in the solution. After removal of trace osmium, the solution is treated with ammonium chloride. This precipitates ruthenium as crystals of ammonium chlororuthenate, NH4RUCI6. The precipitate is washed, dried, and ignited to form ruthenium black. This is reduced with hydrogen at 1,000°C to form very pure ruthenium powder.

Question 7. Why is it correct to write zirconium oxide dichloride for ZrOCl2 but nitro-syl(iv) chloride for NOCI2 ... 

A -alkyl derivatives of tubercidin and of 9-(6-deoxy-6-nitro-j8-D-glucopyrano-syl)adenine have been reported. Guanosine reacted with tetrakis(hydroxy-methyl)phosphonium chloride to give the JV -substituted phosphine (499). The preparation and properties of osmium-ligand complexes of nucleosides are mentioned in Chapter 18. ...
