Abstract

However, this process does not allow the satisfactory introduction of vinylic and benzylic groups (especially in terms of yields given by vinylic organometallics), owing mainly to formation of polymers. Moreover, it is well-known that diketene decomposes violently in the presence of a base. 4 This is a limitation to obtaining high quantities of 3-substituted but-3-enoic acids. We therefore planned a new approach to this type of acids through the reactions between 3- ...
