S. Saito et al., Nucleophilic addition of organomagnesiums to aldimines: Scandium triflate (Sc(OTf)(3)) as an effective catalyst, SYNLETT, (12), 2001, pp. 1859-1861
The 1,2-addition of organomagnesium reagents to p-methoxyphenyl(PMP)amine-d
erived aldimines proceeded effectively in the presence of catalytic amounts
of Sc(OTf)(3).
