Abstract
Whereas the halogen-metal exchange approach from 1,3,5-tribromobenzene (3) to 1,3,5-trilithiobenzene (1) was unsuccessful, 1 was synthesized in high yield (about 80%) by reaction of 3 with LiDBB (lithium 4,4'-d i-tert-butylbiphenyl). Compound 1 was used as the starting material fo r the preparation of other symmetrical trimetalated benzenes, 1,3,5-C6 H3(MgBr)(3) (20), 1,3,5-C6H3(SnMe3)(3) (23), and 1,3,5-C6H3(HgBr)(3) ( 26), by reaction with the corresponding metal halides.
