| The work presented herein describes the syntheses and structure of group 13, 14 and 15 organometallic complexes. Three different ligands were employed in this work: (1) tetraphenylbutadienyl; (2) pentamethylphenyl; and (3) adamantyl.; 1,4-dilithiotetraphenylbutadiene reacts with GaCl3 in the presence of 12-crown-4 to afford [Li(THF)·12-crown-4][(Ph4C 4)Ga(C4Ph4)] (I). Reaction of 1,4-dilithiotetraphenylbutadiene with MX4 (M = Ge, X = Cl or Br; M = Sn, X = Cl) produces Group 14 heterocyclic organometallic complexes (II–IV). Reaction of II with Na2[Fe(CO)4] affords [Ph 4C4GeFe(CO)4(CH3O)Na·C 4H8O2·OEt2]2 ( V).; Utilizing 1,4-dilithiotetraphenylbutadiene with MX3 (M = B or P; X = Br) yields [(Ph4C4)2(C 2H5)]B (VI) and a novel diphosphine, [(Ph 4C4)P—P(C4Ph4)], (VII).; Grignard reagents, RMgX, were also utilized to prepare some organogallium and organoaluminum compounds. Pentamethylphenylmagnesium bromide, (C 6Me5)MgBr, was allowed to react with GaCl3 to give (C6Me5)Ga (VIII). [Mg3Cl 5(Et2O)6][Ada2GaCl2] ( IX) was prepared by reaction of adamantyl-magnesium bromide, AdaMgBr, with GaCl3. Reaction of AdaMgBr with AlCl3 produced [Mg3Cl3Br(OMe2)(Et2O6)][Ada 3AlBr] (X). |
