Facile construction of a novel aminoquinazolinate anionic ligand through organolanthanide-mediated intermolecular nucleophilic addition/cyclization of anthranilonitrile.
Compounds Cp 2Ln[kappa (3)-(4-NH(C 8N 2H 4)(2-NH 2C 6H 4)] [Cp = C 5H 5; Ln = Er ( 1), Y ( 2)] were synthesized by the reaction of Cp 2LnN (i) Pr 2(THF) with anthranilonitrile, indicating a novel organolanthanide-mediated intermolecular nucleophilic addition/cyclization of anthranilonitrile. To trap the intermediate I, a probe reaction of Cp 2ErN (i) Pr 2(THF) with anthranilonitrile and carbodiimide has also been investigated.
