Description

Application

Complex with an (S,S)-phenyl-linked-binaphthol which promotes a catalytic 1,4-addition of malonate to cyclic and acyclic enones. Co-catalyst with CuF-triphenylphosphine in a general catalytic allylation of ketoimines.

In many asymmetric catalysis applications, glove box and Schlenk techniques should be employed to prevent exposure of the rare earth catalyst to air and moisture, which can be detrimental to the reaction outcome. Solutions of the catalyst should be made using anhydrous solvents and used shortly after preparation.
