Organobismuth(III) and dibismuthine complexes bearing N,N′- disubstituted 1,8-diaminonaphthalene ligand: Synthesis, structure, and reactivity

摘要

The organobismuth(III) and dibismuthine complexes bearing N,N′-disubstituted 1,8-diaminonaphthalene ligand were prepared. The reaction of LBiNMe _2 (1) [L = 1,8-(NSiMe _3) _2C _(10)H _6] with ClSiMe _3 results in the elimination of Me _3SiNMe _2, while PhCCH, Cp*H, and PhOH proceed via HNMe _2 elimination and provide the complexes of LBiCl (2), LBiCCPh (3), LBiCp*(4), and LBiOPh (5), respectively. Reaction of 1 with AlMe _3 in n-hexane yields LBiMe (6). Compound 1 reacts with diisopropylcarbodiimide and phenyl isocyanate under insertion at the Bi-NMe _2 bond to give the addition products LBi(N-iPr) _2CNMe _2 (7) and LBiN(Ph)C(O)NMe _2 (8). The reactions of 1 with sulfur and PhSiH 3 result in the formation of LBi-S-BiL (9) and LBi-BiL (10), respectively. Compounds 2-10 were characterized by elemental analysis, ~1H, ~(13)C, and ~(29)Si NMR spectroscopy, and X-ray crystallographic studies.
