摘要：

Succinoylation, acetylation and nitration of 4‐methyldibenzothiophene yields 2‐substituted products. Bromination however, gave 3‐bromo‐4‐methyldibenzothiophene as the major product along with a small amount of the 2‐isomer. The bromo‐compounds were used to prepare related derivatives via lithium exchange. 4‐Methyldibenzothiophene 5,5‐dioxide was also shown to nitrate in the 3‐position. The structures of the derivatives were determined by NMR analyses. An alternative synthesis of 4‐methyldibenzothiophene is described. Copyright © 1969 Journal of Heterocyclic Chemistry
