The reactants are an aryl diazonium salt obtained from reaction of the corresponding aniline with sodium nitrite and hydrochloric acid and the hydrazone of pyruvic acid.
22.
This series of steps is mechanistically identical to the first half of the mechanism formation of the more well-known aryl and alkyl diazonium salts.
23.
Water-soluble diazonium salts react with carbon nanotubes via charge transfer in which they extract electrons from SWNT and form a stable covalent aryl bond.
24.
As a primary amine, the dye can be diazotized in the laboratory, and the resulting diazonium salt used as a trapping agent in enzyme histochemistry.
25.
The reaction of the surface with a solution of diazonium salt in acetonitrile for 2 hours in the dark is a spontaneous process through a free radical mechanism:
26.
So far grafting of diazonium salts on metals has been accomplished on iron, cobalt, nickel, platinum, palladium, zinc, copper and gold surfaces.
27.
The next intermediate is the stable nitrosamine with goes on to lose water forming the diazonium salt which then reacts with the vinyl group in the ring-closing step.
28.
In the Leuckart thiophenol reaction the starting material is an aniline through the diazonium salt ( ArN 2 X ) and the xanthate ( ArS ( C = S ) OR)
29.
The reactive strips detect nitrite by using the aromatic amine ( para-arsanilic acid or sulphanilamide ) in order to form a diazonium salt that in turn reacts with tetrahydrobenzoquinoline to produce a pink azo dye.
30.
The reaction offers a wide scope for both diazonium component and arene component but yields are generally low following the original procedure ( less than 40 % ), given the many side-reactions of diazonium salts.
