摘要:

AbstractThe synthesis is described of various 4‐substituted (1) and 4,6‐disubstituted (2) dibenzothiophenes by lithiation reactions. The factors controlling the formation of 4,6‐disubstituted dibenzothiophenes by the lithiation of 4‐methyl‐ and 4‐ethyl‐dibenzothiophene at the 6‐position versus lithiation at the α‐carbon of the 4‐subs
