Daim ntawv thov
Cerium Trifluoromethanesulfonate yog cerium ntsev ntawm Trifluoromethanesulfonic acid (T790560), muaj zog acid uas yog siv los ua catalyst rau esterification.
Cerium trifluoromethanesulfonate feem ntau yog siv los ua dej-resistant Lewis acid catalyst, thiab feem ntau yog siv rau hauv ib lub lauj kaub synthesis ntawm β-lactam thiab cov tshuaj tiv thaiv nucleophilic ntxiv. Tsis tas li ntawd, nws tseem tuaj yeem siv los ua cov khoom siv hluav taws xob zoo rau epoxide lub nplhaib-qhib cov tshuaj tiv thaiv, muab cov cheeb tsam siab thiab stereoselectivity.
