Sterically Demanding ◽

The reaction of the metal halide with the sterically demanding ligand (i-Pr2C6H3N)(C(Me)(NC6H3-i-Pr2))2 afforded the complexes (i-Pr2C6H3N)(C(Me)(NC6H3-i-Pr2))2MX2 (X = Cl, M = Fe (2), Co (3); X = Br, M = Ni (4), M = Cu (5), Zn (6)). The species of 2 reacts with Li(OEt2)B(C6F5)4 to form the yellow adduct [(i-Pr2C6H3N)(C(Me)(NC6H3-i-Pr2))2Fe(µ-Cl)2Li(OEt2)2][B(C6F5)4] (7) while alkylation of 2 gave (i-Pr2C6H3N)(C(Me)(NC6H3-i-Pr2))2FeClCH2SiMe3 (8). The species [(i-Pr2C6H3N)(C(Me)(NC6H3-i-Pr2))2Ni(η3-C3H5)][B(3,5-CF3C6H3)4] (9) was obtained from reaction of 1 with [(η3-C3H5)NiBr]2 and [Na][B(3,5-(CF3)2C6H3)4] while reaction of 4 with Super-Hydride afforded (i-Pr2C6H3N)(C(Me)(NC6H3-i-Pr2))2NiH2BEt2 (10). X-ray data are reported for 210. The sterically demanding nature of the ligand inhibits subsequent reactivity of these species. Key words: sterically demanding ligands, chelate complexes, X-ray structure, diimine ligands.

Starting Compound

The 6-N(CH3)3-6-CB9H11 carbaborane reacts with sodium in liquid ammonia with the formation of 6-CB9H12- which was used as a starting compound for preparing the 4-CB8H14, 9-L-6-CB9H13 (L = (CH3)2S, CH3CN and P(C6H5)3), 1-(η5-C5H5)-1,2-FeCB9H10-, and 2,3-(η5-C5H5)2-2,31-Co2CB9H10- carboranes. The 4-CB8H14 compound was dehydrogenated at 623 K to give 4-(7)-CB8H12 carborane. Base degradation of 6-N(CH3)3-6-CB9H11 in methanol resulted in the formation of 3,4-μ-N(CH3)3CH-B5H10. The structure of all compounds was proposed on the basis of their 11B and 1H NMR spectra and X-ray diffraction was used in the case of the transition metal complexes.
