Conjugated dienes are highly utilized due to their importance in synthesis and materials research. However, the relative instability of these compounds can make their large-scale preparation and storage slightly difficult. On the other hand, various polyenoic acids are shelf stable and can be easily synthesized or commercially available with low cost. We have developed mild conditions for decarboxylation of polyenoic acids to give the desired polyenes in a good yield. These conditions are selective to carboxylic acids connected to di- or poly-enes. Optimization, generality, and mechanistic studies will be presented.
