RESUMO
The synthesis and structure of new N-(2,6-diisopropylphenyl)-2-phenyldiazenecarboxamide (L2) and N-(2,6-diisopropylphenyl)-2 (perfluorophenyl) diazenecarboxamide (L3) ligands are described. The subsequent reactions of ligands L1, L2 and L3 with trispentafluorophenylboron gave rise to new adducts (A1), (A2) and (A3), where B(C6F5)3 is coordinated to the carbonyl group. New ligands and adducts are characterized by nuclear magnetic resonance (NMR), infrared (IR), and elemental analysis techniques. The crystal structures of all compounds are obtained and described.
