<prompt> Bheka isigaba esingezansi bese uphendula umbuzo emva kwalokho ngolimi olufanayo nesigaba: Ukudlula: I-methyllithium i-reagent elula kunazo zonke ye-organolithium enefomula yokuhlola i-CH3Li. Le nhlanganisela ye-s-block organometallic yamukela isakhiwo se-oligomeric kokubili ekuxazululeni nasesimweni esiqinile. Le nhlanganisela ephendula kakhulu, evame ukusetshenziswa njengesixazululo kuma - ether, iyisisetshenziswa ekuhlanganisweni kwezinto eziphilayo kanye nasekhemikhali le-organometallic. Imisebenzi ehilela i-methyllithium idinga izimo ezingenamanzi, ngoba le nhlanganisela iphendula kakhulu emanzini. I-oxygen ne-carbon dioxide nazo azihambisani ne-Meli. Ngokuvamile i-methyllithium ayilungiswa, kodwa ithengwa njengesixazululo kuma-ether ahlukahlukene. Umbuzo: Le nhlanganisela iba nesakhiwo esinjani?  <response>: isakhiwo se-oligomeric
