Abstract

2-Dialkylamino- and 2-piperidino-1,4-naphthoquinones with a methyl group in position 3 or 5(8) of the naphthoquinone were synthesized by reacting dimethyl- and diethylamines and piperidine with 2- and 5-methyl-1,4-naphthoquinones. The quantum yields of photoconversion of the synthesized compounds in benzene were determined. A 1.2- to 6.5-fold increase of the quantum yield over that of 2-dimethylamino-1,4-naphthoquinone was established. A comparison of the quantum yields with the calculated charges on the reaction centers in the excited (T 1) state showed that there is not a linear relationship between them.
