Synthesis and Characterization of (4-Fluorophenyl)amino-Based Amino- and Iminometallanes of Group 13. Crystal Structures of (MeAlNR f ) 4 , (MeMNR f ) 6 ?? n THF (M = Al, n = 2; M = Ga, n = 7), and (MeIn(THF)NR f ) 4 (R f = 4-C 6 H 4 F)

The novel amino- and iminometallanes (MeAlNR(f))(n) (1) (n = 4, 1a; n = 6, 1b), (Me(2)GaN(H)R(f))(2) (2), (MeGaNR(f))(6) (3), (Me(2)InN(H)R(f))(2) (4), and (MeIn(THF)NR(f))(4) (5) (R(f) = 4-C6(5)H(4)F) have been prepared in high yield by the reaction of AlMe(3), GaMe(3), and InMes(3), respectively, with 4-fluoroaniline. All of the products have been fully characterized by elemental analysis, IR, NMR, and mass spectroscopy. The crystal structures of 1a, 1b . 2THF, 3 . 7THF, and 5 have been determined. For the degree of oligomerization of compound 1 a solvent- and temperature-dependent influence is assumed. (MeGaNR(f))(6) (3) is the first hexameric iminogallane and (MeIn(THF)NR(f))(4) (5) is the second iminoindane described in the literature.
