Transition metal halides reactions with organolithium compounds

Ge—metal bonds can be built in analogy as described for Ge—C bonds by the reaction of organolithium compounds with metal halides. With trans-dichlorobis(triethylphosphine)platinum(II), new germyl transition metal complexes were synthesized (equation 36)41. 

Allyl complexes of the transition metals are most commonly synthesized by reactions of Grignard compounds or organolithium derivatives with halides or acetylacetonates of the transition metals. Dependent upon the starting material, complexes containing exclusively allyl groups (homoleptic complexes) may be obtained, or derivatives also possessing other ligands (heteroleptic complexes) may be prepared ...
