Rare-earth metal-mediated addition/cyclization of the 2-cyanobenzoamino anion†
Abstract
Reaction of two equiv of [2-NCC6H4HNLi(THF)]n (1) with Cp2LnCl(THF) yields the heterobimetallic complexes Cp2Ln[κ3-(4-NH(C8N2H4)(2-NHC6H4)]Li(THF)3 (Cp = C5H5; Ln = Er (2), Y(3)), indicating an organolanthanide-mediated nucleophilic addition/
