Phenyllithium翻译
WebPreparative Methods: prepared from phenyl halide (PhCl, 2 j PhBr, 2 k,l PhI 2 m) and lithium metal in ether. Several procedures have been used to prepare solid, salt-free PhLi. 2 n–r The synthesis of 13 C-labeled PhLi ( ipso carbon only) has been described. 2 h. Handling, Storage, and Precautions: moisture and oxygen sensitive. WebPhenyllithium can also be used to modify the properties of phenylsodium. Ordinarily, phenylsodium reacts violently with diethyl ether, but Georg Wittig showed that by synthesizing PhNa with PhLi in ether, the complex (C 6 H 5 Li)(C 6 H 5 Na) n was formed. The phenylsodium component of the complex reacts before the phenyllithium, making it …

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. WebAnother explanation is suggested, in which the phenyllithium is supposed to be added directly to the carbonyl bond (without previous formation of lithium salt) yielding an intermediary product (C 6 H 5 COOLi), which by phenyllithium is brought over into the alcohol in accordance with the reaction above.. When using methyllithium, however, these …
