Iyini i-Methyllithium CAS 917-54-4?

I-Methyl lithium iyi-reagent ye-organolife. Ama-S-zone organometallic compounds axutshwe nge-oligomer kokubili okuqinile kanye nesisombululo. Le nhlanganisela esabela kakhulu ivame ukusetshenziswa ekwakhiweni kwama-ether futhi isetshenziswa ekwakhiweni kwezinto eziphilayo kanye ne-organometallic chemistry. Ukusabela okubandakanya i-Chemicalbook kanye nayo kudingeka kwenziwe ezimweni ezingenamanzi ngoba isabela ngamandla namanzi. I-oxygen kanye ne-carbon dioxide akukwazi ukuhambisana nayo. Ngakho-ke, i-methyl lithium ngokuvamile ayilungiswa kusengaphambili ngaphambi kokusetshenziswa, kodwa ingancibilikiswa ezixazululweni ezahlukene ze-ether ukuze igcinwe.

Isicelo

I-Lithium methyl iyi-organic base evamile kanye ne-methylation reagent, esetshenziswa kabanzi ekuhlanganiseni i-organic kanye ne-catalyst. I-Methyllithium ingaxuba i-methylate emaqenjini ahlukahlukene asebenzayo, ingasusa amaqembu avikelayo, ihlanganise amanye ama-methylated organometallic reagents, ingasetshenziswa njengesisekelo futhi inciphise izinsimbi zokuguquka. Izinyibilikisi nama-halogen anethonya elikhulu ekusabeleni kusetshenziswa i-methyl lithium engaxubaniswanga.
