Abstract:
A macrocycle, 6, has been synthesized in high yield from 2,5-
di(pyrazol-1-yl)hydroquinone and 1,1'-fc[B(Me)NMe2](2) {fc =
Fe(C5H4)(2)}. The molecule incorporates two redox-active 1,1'-
ferrocenylene units in its backbone and contains four chiral
boron centers, each of them possessing the same configuration.
It is demonstrated that crystal structures of organometallics
of moderate complexity can be solved from high-resolution X-ray
powder diffraction patterns, once the connectivity between the
functional groups is known.
