1,2-Bis(imino)acenaphthene complexes of molybdenum and nickel

Abstract

Molybdenum hexacarbonyl reacts with 1,2-bis[(2,6-diisopropylphenyl)imino]acenaphthene (1, dpp-BIAN) and 1,2-bis[(trimethylsilyl)imino]acenaphthene (2, tms-BIAN) in toluene to produce (dpp-BIAN)Mo(CO)4 (3) and (tms-BIAN)Mo(CO)4 (4), respectively. The reaction of [CpNi(CO)]2 with 1 yields (dpp-BIAN)NiCp (5). Metathesis between Li2(tms-BIAN) and NiCl2(dppe) affords the Ni(0) complex (tms-BIAN)Ni(dppe) (6). The diamagnetic compounds 3, 4 and 6 have been characterized by 1H, 29Si and 31P NMR spectroscopy, IR spectroscopy and elemental analysis. The ESR spectrum of the paramagnetic compound 5 indicates the presence of Ni(I) coordinated by Cp and a neutral dpp-BIAN ligand. The molecular structures of 3–6 have been determined by single-crystal X-ray analysis.
