The homodienyl-[1,5]-hydrogen shift in vinylaziridines 4a-h has been investigated. It has been found that substituents capable of conjugation at the rearrangement origin will reduce the reaction time while substituents on the vinyl moiety affect the rate most notably when they are capable of interfering sterically with the other ring substituents.
