Ethyl cis-3-Iodoacrylate, stabilized with copper chips, is primarily utilized in organic synthesis as a versatile building block for constructing complex molecules. Its application is prominent in the formation of carbon-carbon bonds, particularly in coupling reactions such as the Heck reaction, where it serves as an effective electrophile. The compound is also employed in the synthesis of fine chemicals, pharmaceuticals, and agrochemicals, where its iodine atom can be readily substituted or participate in further transformations. Additionally, it is used in the preparation of conjugated systems and polymers, contributing to the development of materials with specific electronic or optical properties. The stabilization with copper chips ensures its reactivity is maintained during storage and handling.
