A europium complex, [Eu(dppm)3], can ‘recognize’ the difference in not only the protecting groups of α- or β-alkoxy aldehydes but also the size of ketene silyl acetals and catalyse either the chelation or nonchelation controlled-aldol reaction; {[Eu(dppm)3]= tris[di(perfluoro-2-propoxypropionyl)methanato]europium(III)}.
