Allylation of aldehydes with potassium allyltrifluoroborate catalyzed by lanthanide-based metal-organic framework

Abstract

The use of the framework [Eu2(fum)3(H2O)4]·(3H2O), Eu-MOF, as catalyst for allylation of aldehydes by potassium allyltrifluoroborate is described. The method features the use of small catalyst loads and wet solvents, and the products were obtained in high yields, short reaction times, at room temperature with no further purification. The catalyst was recovered and reused up to six times in further allylation reactions without significant loss in the yields.
