Silver compounds reactions

Catalysts. Silver and silver compounds are widely used in research and industry as catalysts for oxidation, reduction, and polymerization reactions. Silver nitrate has been reported as a catalyst for the preparation of propylene oxide (qv) from propylene (qv) (58), and silver acetate has been reported as being a suitable catalyst for the production of ethylene oxide (qv) from ethylene (qv) (59). The solubiUty of silver perchlorate in organic solvents makes it a possible catalyst for polymerization reactions, such as the production of butyl acrylate polymers in dimethylformamide (60) or the polymerization of methacrylamide (61). Similarly, the solubiUty of silver tetrafiuoroborate in organic solvents has enhanced its use in the synthesis of 3-pyrrolines by the cyclization of aHenic amines (62). 

The regiochemistry is determined by the regiochemistry of the fluoride ion addition reaction, that is, via the most stable perfluorocarbanion intermediate Von Werner used a similar reaction to prepare silver compounds from perfluoro-2-methyl-2-butene and perfluoro 2 methyl-2-pentene [271] Silver(I) fluoride adds to bis(ttitluoromethyl)ketene in DMF without fluoride ion catalysis [270] The analogous trifluorovinylsulfurpentafluoride reacts similarly to give the isolable pentafluorosulfur derivative [272] (equation 187)... 

Tfifluorovinyl- and ( 0-pentafluaropropenylsilver compounds can be prepared via the exchange reaction of the corresponding cadmium compound with silver trifluoroacetate [144] (equation 189) The 2-pentafluoropropenyl silver compound can be synthesized via a similar exchange reaction of silver tnfluo-roacetate with 2-pentafluoropropenyllithium [279]... 

A highly explosive liquid [1]. Early attempts failed to isolate it but prepared numerous other explosive compounds. Reaction of dichlorine hexoxide with silicon tetrachloride or tetrabromide gave an explosive solid, apparently a perchlorato oligosiloxane. Silver perchlorate and silicon tetrahalides in ether gave explosive volatile organics, perhaps ethyl perchlorate. Replacing ether by acetonitrile as solvent, a solid (di)acetonitrile adduct of the tetraperchlorate precipitated, described as exceptionally explosive even in the smallest quantities [2],... 

The silver compound is stable at room temperature but the corresponding n-C3F7 and CF3 compounds appear to decompose above -100°C. Mention is also made of CuC6F5 and AgC6F5 being formed in analogous reactions (57). Gold atoms react with methyl iodide in the presence of dimethylsulfide ... 

Effect of Light on the Decomposition of Silver Chloride. Introduce 2 ml of a 0.1 W silver nitrate solution into a test tube and add dropwise such an amount of a saturated sodium chloride solution that will be sufficient for the complete precipitation of the silver as -a chloride. Rapidly filter out the precipitate, rinse it with water and put it on two watch glasses. Place one glass with the precipitate in a dark cupboard, and leave the other at a window in daylight. In an hour, compare the colour of the precipitates and explain the phenom->ena you observe. How does light affect the reaction After the experiment, put the precipitates containing a silver compound into he jars set aside for them. 

Put a small amount of the compound into a test tube and test how it is affected by heating. Treat the remaining silver compound with a 25% ammonia solution. What happens Write the equations of the reactions.

A fire and explosion reulted from encapsulating nuclear waste [15], consisting mostly of sodium nitrate, in asphalt. The full details of the reaction reported are complex, the principles simple [12]. Nitrate/asphalt has previously seen application as rocket fuel and may have been behind Greek Fire [Editor]. A more theoretical study, also looking at the influence of silver compounds has appeared [13]. 

In a review of explosions involving derivatives of gold, silver and platinum, reactions of ammonia with gold and silver compounds, and of hydrogen in presence of platinum compounds are emphasised. 

Silver nitrate test The compound to be tested is treated with a few drops of 1% alcoholic silver nitrate. A white precipitate indicates a positive reaction. This could be due to either silver chloride (reaction with a reactive alkyl halide), silver alkynide (reaction with a terminal alkyne), or the silver salt of a carboxylic acid (reaction with a carboxylic acid).
