Synthesis
Phenylsilver can be produced by treating silver nitrate with trialkylphenyltin (or trialkylphenyllead at −10 °C). In the presence of excess silver nitrate, the reaction produces the bright yellow complex C6H5Ag·2AgNO3.[1] Phenylsilver can also be produced by treating silver nitrate with diphenylzinc in a 1:2 molar ratio and 0 °C. If the molar ratio is 1:1, it will produce orange C6H5Ag·2AgNO3.[3] Earlier syntheses using phenyl magnesium bromide will produce phenylsilver that contains silver or magnesium salt impurities, which destabilize it.[3][4]
When heating phenylsilver at a speed of 5 °C/min, it decomposes at 67 °C. If the heating speed is 10 °C/min, it will explode at 47 °C.[1]
