Lanthanum trifluoromethanesulfonate yog siv rau hauv Aldol cov tshuaj tiv thaiv ntawm silyl enol ethers nrog aldehydes.Nws yog ib qho txiaj ntsig zoo rau cov tshuaj tiv thaiv Baylis-Hillman.Nws kuj catalyzes Michael ntxiv rau methyl vinyl ketone hauv dej.
Lewis acid uas ua rau cov dej tsis zoo siv hauv Aldol cov tshuaj tiv thaiv ntawm silyl enol ethers nrog aldehydes.
