{(R,S (Fc),S (Fc))-2′′-Bromo-2-[1-(dimethylamino)ethyl-κN]-1,1′′-biferrocene}trihydridoboron
The title structure, [Fe(2)(C(5)H(5))(2)(C(14)H(19)BBrN)], contains a chiral and asymmetrically 2,2′′-disubstituted biferrocene designed as precursor for enantioselective non-C (2)-symmetric biferrocenyldiphosphine catalysts. The mean bond lengths in the biferrocene unit are Fe—C = 2.048 (10) Å and...

description | The title structure, [Fe(2)(C(5)H(5))(2)(C(14)H(19)BBrN)], contains a chiral and asymmetrically 2,2′′-disubstituted biferrocene designed as precursor for enantioselective non-C (2)-symmetric biferrocenyldiphosphine catalysts. The mean bond lengths in the biferrocene unit are Fe—C = 2.048 (10) Å and C—C = 1.427 (8) Å within the cyclopentadienyl rings. The B—N bond lengths of the BH(3) protected amine is 1.631 (3) Å. The interplanar angle between the two connected cyclopentadienyl rings is 54.29 (8)° and the corresponding Fe—Cg—Cg—Fe torsion angle is −52.5°. The conformation of the molecule is stabilized by an intramolecular C—H⋯Br interaction. |
