Replacement synthesis characteristics

PTC has been applied in the synthesis or organic compounds since the late 1960s, and its applications have expanded rapidly, especially during the 1980s and 1990s. Some process characteristics which could render the replacement of a non-PTC process with a PTC process attractive are (Starks et al., 1994) ... 

Solid-phase methods are applicable to syntheses of sequence-specific oligomers and dendritic structures. The triazene chemistry developed for this specific purpose may also be useful in other types of syntheses. Further development of solid-phase syntheses of this type into combinatorial synthesis of oligomers is the next logical step. Solid-phase methods will never completely replace solution-phase approaches to oligomers, but either technique should be considered with respect to the special characteristics and requirements for the system under investigation.
