Abstract

Both organomagnesium compounds (Grignard reagents) and organolithium compounds are of utmost importance in synthesis. New developments in the area of difunctional organometallic compounds will be described against a historical background in which the author’s interest gradually drifted from organolithium chemistry, in particular the deep red ortho-dilithiobenzene, to its magnesium analogue, the tetrameric ortho-phenylenemagnesium. The latter was applied in the synthesis of novel 1,2-disubstituted benzene derivatives such as 9,10-dimetallatriptycenes.
