Chemically, the polymerization reaction can be seen as a condensation reaction.

PO can be seen as the end product of condensation reactions, where each tetrahedron shares three corners with the others.

Its original preparation demonstrated the scope of condensation reactions to construct new, complex organic compounds.

This process is the one that usually initiates condensation reactions.

Variations to this process are possible using poly(dichlorophosphazene) made by condensation reactions.

Other synthetic methods include the condensation reactions of organic-substituted phosphoranimines.

As mentioned above, a condensation reaction is also an acid-base reaction.

PbO is used in certain condensation reactions in organic synthesis.

It is also active in the condensation reaction in heme synthesis.

Pyridine is also used as a base in condensation reactions.
