Preparation and NMR spectra of four isomeric diformyl[2.2]paracyclophanes (cyclophanes 66)
Four isomeric dialdehydes 4, readily available from cycloaddition of propiolic aldehyde (2) to 1,2,4,5-hexatetraene (1), were separated by chromatography and recrystallization, and were characterized by their spectroscopic data. The individual isomers can now be easily identified from their 1H NMR s...
