Abstract
A reaction of diphenyl carbonate and various diols provides highly valuable cyclic carbonates in the presence of 1,5,7-triazabicyclo[4.4.0]dec-5-ene (TBD) as organocatalyst. This practical, safe, and highly efficient carbonylation system successfully replaced highly toxic and unstable phosgene or its derivatives while maintaining the desired high reactivity. Moreover, this new system can be used to synthesize sterically demanding cyclic carbonates.
