Abstract
The syntheses and structures of new bis-N-phenyl-4-cyano-β-diketiminate (1), bis-N-phenyl-2-cyano-β-diketiminate (2), N-phenyl-4-cyano-N-phenyl-2-cyano-β-diketiminate (3), N-phenyl-4-cyano-N-2,6-diisopropylphenyl-β-diketiminate (4), N-phenyl-2-cyano-N-2,6-diisopropylphenyl-β-diketiminate (5), and methallyl nickel complexes [L1Ni(η3-methallyl)] (6), [L2Ni(η3-methallyl)] (7), [L4Ni(η3-methallyl)] (8), and [L5Ni(η3-methallyl)] (9) from the reaction of deprotonated ligands 1/2, 4/5, and methallylnickel chloride dimer are reported. Subsequent reactions of complexes 6–9 with tris(pentafluorophenyl)boron give rise to new adducts [L1Ni(η3-methallyl)]·2B(C6F5)3 (10), [L2Ni(η3-methallyl)]·2B(C6F5)3 (11), [L4Ni(η3-methallyl)]·B(C6F5)3 (12), and [L5Ni(η3-methallyl)]·B(C6F5)3 (13), where B(C6F5)3 is coordinated to the cyano group. New compounds are characterized by NMR, IR, and mass spectrometry techniques, and crystal structures of most compounds are obtained and described. Complexes 6–9, adducts 10–13, and adducts 1...
