The process begins with two phosphate units coming together in a condensation reaction. 2 H(PO4)2−⇌ (P2O7)4−+ H2O The condensation is shown as an equilibriumbecause the reverse reaction, hydrolysis, is also possible.
WebThe amide is converted to the nitrile by careful heating in the presence of the dehydrating agent phosphorus pentoxide. Amides can be reduced to amines by catalytic hydrogenation or by reaction with lithium aluminum hydride. Amides can also react with hypohalites to form primary amines with one less carbon atom.
