Synthesis and Characterization of (4-Fluorophenyl)amino-Based Amino- and Iminometallanes of Group 13. Crystal Structures of (MeAlNRf)4, (MeMNRf)6·nTHF (M = Al, n = 2; M = Ga, n = 7), and (MeIn(THF)NRf)4 (Rf = 4-C6H4F)

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-C 6 H 4 F) have been prepared in high yield by the reaction of AlMe 3, GaMe 3, and InMe 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.
