Abstract: The synthesis of three adducts of ferrocene boroxine (C10H9Fe)3B3O3 with dative bonds
to amines (pyridine, 4-picoline, 4-aminomethyl pyridine, and p-bromoaniline), as well as
to two diamines (4,4-bipyridine and 1,4-diazabicyclo[2.2.2]octane) to form bis-complexes
which have the potential to be simple molecular rotors was completed. In a related
project, complexes of either diphenylborinic acid or 9-borabicyclononane with Lewis
base/ hydroxyl group pairs (picolinic acid, nicotinic acid, isonicotinic acid, picolinic acid
N-oxide, nicotinic acid N-oxide, isonicotinic acid N-oxide, benzoic acid, 3,5-
dibromobenzoic acid, 2-pyridinmethanol, L-Leucine, and L-Phenylalanine) were formed.
These primarily intramolecular reactions formed rings of either 5 or 6 atom members.
There was also evidence that some of the more geometrically challenged systems could
form dimers. The characterization of all of these complexes was performed by 1H NMR
and, when possible, LCMS and single crystal x-ray diffraction.
