ABSTRACT
This chapter describes terminal transformation reactions of telechelics which have gained general attention or are impressive by their unconventional approach. Three main classes of synthetic compounds can be distinguished in organic and polymer chemistry: monomers, oligomers, and polymers. The amino function represents an important reactive group and has received considerable attention in terminal transformation studies of telechelics. The aldehyde telechelic was relatively stable similar to an analogously prepared aldehyde attached to a cross-linked polymer. Amides as carboxylic acid derivatives have found only limited interest in telechelic chemistry. Hydroxyl telechelics play a less important role when considering the hydroxyl group as a target function of terminal conversion reactions. Halogeno-terminated polymers can be used as prefunctional derivatives for further end-group transformations. In order to demonstrate the versatility of terminal conversion and to provide some exceptional examples of end-group transformation some telechelic modification reactions by uncommon groups are presented.
