Abstract
Based on lithium anthracenes RLi, the formation of mixed complexes from organolithiums and lithium salts RLi·LiX is illustrated. The [RLi(L)](2) dimers formed in presence of different donating solvents L as well as the corresponding mixed lithium bromide complexes [RLi(L)·LiX] were isolated and structurally characterized.
Highlights
Based on lithium anthracenes RLi, the formation of mixed complexes from organolithiums and lithium salts RLiÁLiX is illustrated
Since their discovery by Schlenk and Holtz in 1917,1 organolithiums have emerged as the leading tool in organometallic chemistry.[2]
Aside from their strong nucleophilic characteristics, organolithiums are as easy to handle as they are synthesized, which broadens their spectrum of application from research laboratory work[3] to large scale industrial processes.[4]
