Phenyllithium C6H5Li ChemSpider
Phenyllithium or lithobenzene is an organometallic agent with the empirical formula C6H5Li. It is most commonly used as a metalating agent in organic syntheses and a substitute for Grignard reagents for introducing phenyl groups in organic syntheses. Crystalline phenyllithium is colorless; however, solutions of … See more Phenyllithium was first produced by the reaction of lithium metal with diphenylmercury: (C6Η5)2Ηg + 2Li → 2C6Η5Li + Ηg Reaction of a phenyl halide with lithium metal produces … See more Phenyllithium is an organolithium compound that forms monoclinic crystals. Solid phenyllithium can be described as consisting of dimeric Li2Ph2 subunits. The Li atoms and the ipso carbons of the phenyl rings form a planar four-membered ring. The plane of the … See more The primary use of PhLi is to facilitate formation of carbon-carbon bonds by nucleophilic addition and substitution reactions: PhLi + R2C=O → … See more WebOne involves combination of 18 with 1 equiv of phenyllithium and 1 equiv of carbon monoxide, followed by elimination of 1 equiv of lithium oxide, yielding 17, the lithium enolate of 2; a second involves combination of 18 with 1 equiv of phenyllithium and 2 equiv of carbon monoxide, yielding 22, the trilithium trianion of 8.
