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.
