- Synthesis of Some 4-Substituted and 4,6-Disubstituted Dibenzothiophenes
-
The 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-substituent are examined.
