摘要: Abstract Direct one-stage photocyclization of trans-4-styrylquinoline to dihydrobenzo[i]phenanthridine (DHBP) in n-hexane with a quantum yield 0.013 was observed. The kinetics the photochemical transformations and an effect excitation intensity on DHBP were studied. In ethanol proceeded two stages intermediate formation cis-isomer ground state. These facts imply diabatic reaction pathway for trans-to-cis photoisomerization 4-styrylquinoline adiabatic hexane.
