Chapter 14   Conjugated Dienes and Ultraviolet Spectrocopy

The following are items that you need to know for Exam V:

Conjugated dienes:

a) preparation

b) electrophilic addition

UV spectra measure conjugated systems in terms of wavelength position

and intensity e = A/C x l

Diels-Alder Reaction = [4 + 2] cycloaddition to produce cyclohexenes

facilitated by:

EWG - dienophile

ERG - diene
