Ullmann Reaction - Organic chemistry

In a step-reaction polymerization reaction, sometimes called condensation polymerization, the polymer chains grow by reactions that occur between two molecular species. An example is the polymerization reaction involving terephthalic acid and ethylene glycol, both of which are bifunctional.

Since synthesis reactions are the reverse of decomposition, you might ask if the decomp.

The general pattern of a synthesis reaction is:
A + B --> AB
Note that in order for the reaction to occur and a compound to form, one of the elements must be able to give electrons (cation) and the other element must be able to gain electrons (anion).

In a synthesis (or combination) reaction you start out with two separate elements on the reactants side and combine them to form a compound on the products side.

One example and perhaps the most important one in life is the process of photosynthesis which is the process of converting light energy in chemical energy and storing it in the bonds of sugar.

Synthesis of Methyl Orange - Reaction Mechanism - …

Polyesters are condensation polymers, which contain fewer atoms within the polymer repeat unit than the reactants because of the formation of byproducts, such as H2O or NH3, during the polymerization reaction. Most synthetic fibers are condensation polymers.

Styrene is an example of a vinyl monomer - a small molecules containing carbon-carbon double bonds. A few other important vinyl monomers are listed below4. Some of these polymers are synthesized by methods involving initiators other than free radicals - carboanions, carbocations, or coordination compounds, for instance. Vinyl polymers are addition polymers, which have the same atoms as the monomer in their repeat units.

Sonochemical Reaction and Synthesis - Hielscher

Here is one more category of decomposition reactions:

CaO + H2O ---> Ca(OH)2
Na2O + H2O ---> NaOH
N2O5 + H2O ---> HNO3
P2O5 + H2O ---> H3PO4
The first two substances are metallic oxides and the last two are nonmetallic oxides.

Sonochemical Reaction and Synthesis

Here's another example of a synthesis reaction:

H2 + O2 ---> H2O2
This happens to be a reaction that can never take place.

Organic Synthesis - Organic Chemistry Portal

Here's an example:

CO2 + H2O ---> C6H12O6 + O2
You might recognize this as the photosynthesis equation.

A+ synthesis of metronidazole chemical reaction | …

Synthesis can also be two compounds making a more complex compound (or a compound and an element joining together) as in these examples:

CaO + CO2 ---> CaCO3
Na2O + CO2 ---> Na2CO3
KCl + O2 ---> KClO3
Ba(ClO3)2 ---> BaCl2 + O2
Notice how, in every case so far, there is only one substance on the right-hand (product) side.

Oxime synthesis by oxidation or redox reaction

Chain-reaction polymerization, sometimes called addition polymerization, requires an initiator to start the growth of the reaction. The largest family of polymers 3, vinyl polymers, are produced by chain polymerization reactions. A good example is the free-radical polymerization of styrene, which is initiated by a free radical (R) that reacts with styrene. The compound that is formed still is a free radical, which can react again.
