Telomerization

Telomerization is a reaction that produces a particular kind of oligomer with two distinct end groups. The oligomer is called a telomer. Some telomerizations proceed by radical pathways, many do not. A generic equation is: : where M is the monomer, and A and B are the end groups, and n is the degree of polymerization. One example is the coupled dimerization and hydroesterification of buta-1,3-diene. This step produces a doubly unsaturated C9-ester: :2 CH 2 =CH-CH=CH 2 + CO + CH 3 OH → CH 2 =CH(CH 2 ) 3 CH=CHCH 2 CO 2 CH 3 The monomer in this reaction is butadiene, the degree of polymerization is 2, and the end groups are vinyl and the carboxy methyl (CO 2 CH 3 ). This and several related reactions proceed with palladium catalysts. Many telomerizations are used in industrial chemistry.

Fluorotelomers are an example. ==See also== Perfluorooctanoic acid (synthesis) Telomerization (dimerization) ==References==
