Abstract

The photorearrangement of 2-aryl-4-methylpent-2-enenitriles to arylcyclopropanes is discussed on the basis of substituent effect. The efficiency of 1, 2-hydrogen migration is independent from an electronic effect of the substituent and correlated to the singlet energy of excited molecule.
