The allenes 1 directly connected with an electron-withdrawing substituent have been used successfully as synthetic building blocks for more than four decades (see Scheme 7.1). The polarization of the C=C double bonds by the acceptor substituent allows a wide and very useful range of subsequent reactions, for example nucleophilic additions, cycloadditions and miscellaneous syntheses of heterocydes. 

Miscellaneous Routes. Polyamides have been prepared by other reactions, including addition of amines to activated double bonds, polymerization of isocyanates, reaction of formaldehyde with dinitriles, reaction of dicarboxylic acids with dllsocyanates, reaction of carbon suboxide with diamines, and reaction of diazlactones with diamines. These reactions are reviewed in Reference 4. 

Miscellaneous and Anomalous Ozonolysis. Numerous cases of nearby alcohols and other functional groups participating in novel fragmentation of the ozonide can be found however, their general use in synthesis is somewhat limited. In addition, anomalous ozonolysis, usually defined as an ozonolysis reaction where the double bond as well as an adjacent single bond is cleaved, can be found throughout the literature. Most of these miscellaneous... 

In conclusion, stilbenes involve in miscellaneous chemical reactions. For non-substituted stilbenes, the most chemically reactive part is double bond, which relatively easily undergoes the halogenation, epoxidation, oxidation, reduction, and addition. The chemistry of substituted stilbenes is in principle as rich as organic chemistry. Including stilbenes in dendrides, dextrins, polymers, and surfaces led to a sufficient change in their chemical, photochemical, photophysical, and mechanical properties and, therefore, establishes the basis for design of new materials.
