| Abstract: | Reaction of two equiv of 2-NCC(6)H(4)HNLi(THF)](n) (1) with Cp(2)LnCl(THF) yields the heterobimetallic complexes Cp(2)Lnκ(3)-(4-NHdouble bond, length as m-dash](C(8)N(2)H(4))(2-NHC(6)H(4))]Li(THF)(3) (Cp = C(5)H(5); Ln = Er (2), Y(3)), indicating an organolanthanide-mediated nucleophilic addition/cyclization of the 2-cyanobenzoamino anion to construct the 4-iminoquinazolinate dianionic ligand. |
