摘要：

nBuLi first reacts with BrHgC(SiMe3), at 65–700C in the melt to give the title compound within an hour. This is monomeric in solution and dimeric in the crystal (structure on the right), a novel structural type for solvent‐free alkyllithium compounds. Apart from the two direct bonds from Li to the carbanionic C‐atoms there are also agostic interactions with two H atoms of the SiMe3 substituents, so that each Li atom is coordinated altogether in a distorted tetrahedral fashion.
