General description

2,3,5,6-Tetrafluorobenzaldehyde is a polysubstituted benzaldehyde and was evaluated as a substrate of PmHNL (Prunus mume hydroxynitrile lyase). Reaction of 2,3,5,6-tetrafluorobenzaldehyde with dipyrromethane was reported.

Application

2,3,5,6-Tetrafluorobenzaldehyde was used in the preparation of 1,3-bis(2,4,6-trimethylphenyl)-2-(2,3,5,6-tetrafluorophenyl)imidazolidine and 1,3-dimethyl-2-(2,3,5,6-tetrafluorophenyl)imidazolidine.

The synthesis of N-heterocyclic carbene (NHC) adducts by condensation of diamines with appropriately substituted benzaldehydes is described. This simplified approach provides the NHC adduct without first having to generate the carbene followed by its protection. These adducts undergo thermal deprotection
