N2 - The photochemical reactions of several 1-arylpropenes with diethylamine and trimethylamine in hexane and acetonitrile solution have been investigated. The amines quench the fluorescence of the singlet 1-arylpropenes with rate constants which are dependent upon the aryl substituent. The formation of fluorescent exciplex intermediates is observed for some of the 1-arylpropenes with triethylamine. Preparative irradiation results in the formation of 1-arylpropene-amine adducts as well as 1-arylpropene isomerization, reduction, and dimerization. In the case of 1-phenyl-propene a single adduct is formed with either diethylamine or triethylamine. Mixtures of regioisomeric adducts are formed in the reactions of some of the 1-arylpropenes. The effects of aryl substituents upon exciplex formation and photochemical behavior are discussed.
