Cyclic-voltammetric measurements show that 2-methylnaphthalene-1,4-diacetat
e is electrochemically oxidized on glassy-carbon electrode in glacial aceti
c acid at + 1.45V vs SCE. The process is irreversible and diffusion control
led. Preparative controlled-potential electrolysis indicates that 2-methyl-
1,4-naphthoquinone is a sole product. The material and current yields of th
e process are 94 and 99%, respectively.
