Rare earth(III) perfluorooctane sulfonates (RE(OPf)3) catalyze the efficient aldol condensation of different ketones with various aromatic aldehydes in fluorous solvents without the occurrence of any self-condensations. By simple separation of the fluorous phase containing only catalyst, reaction can be repeated several times.
稀土(III)全氟辛烷磺酸盐(RE(OPf)3)在氟溶剂中催化不同酮与各种芳族醛的有效羟醛缩合反应,而不会发生任何自缩合反应。通过仅含催化剂的氟相的简单分离,反应可重复数次。
