Triethyl orthoformate is an orthoester of formic acid. It is commercially available. The industrial synthesis is from hydrogen cyanide and ethanol.[1]
It may also be prepared from the reaction of sodium ethoxide and chloroform:[2]
- CHCl3 + 3 Na + 3 EtOH → HC(OEt)3 + 3/2 H2 + 3 NaCl
Triethyl orthoformate participates in the Bodroux-Chichibabin aldehyde synthesis, for example:[3]
