Abstract
Abstract Nowadays, organic carbonates are becoming widely used as solvents due to their low toxicity, as monomers for the preparation of polymers, and several other uses. The use of carbonates as monomers to form polymers, in particular, may expand in the near future causing a large increase of their demand on the world market. As the current and conventional synthetic technology is represented by the use of phosgene (that is banned in several countries) as a building block, the development of new synthetic methodologies for organic carbonates is receiving much attention worldwide. The replacement of such toxic raw material with carbon dioxide or urea seems to be very attractive and interesting. In fact, it responds to the “green chemistry” principles by using clean and safe technologies, also implementing the atom-economy strategy. In this chapter, the processes used for the synthesis of either linear or cyclic carbonates alternative to the use of phosgene will be considered, covering both the rich patent and scientific literature.
