WitrynaIn organic chemistry, an imine (/ ɪ ˈ m iː n / or / ˈ ɪ m ɪ n /) is a functional group or organic compound containing a carbon–nitrogen double bond (C=N).The nitrogen atom can be attached to a hydrogen or an organic group (R). The carbon atom has two additional single bonds. Imines are common in synthetic and naturally occurring compounds and … Witryna27 lis 2024 · Considering that the ketone-amine condensation to generate imine would be a prerequisite step in this reaction, we turned our attention to using Lewis acid …
