摘要：

1,2-Bis(dimethylamino)-1,2-dibora-[2]ferrocenophane (1) was prepared by the reaction of 1, 1'-dilithioferrocene with 1,2-dichlorobis(dimethylamino)diborane(4). In addition to hindered rotation about the B-N bond (Delta G double dagger > 80 kJ mol(-1)), another dynamic process was revealed by H-1 and C-13 NMR in solution at low temperature, and interpreted as motion of the cyclopentadienyl rings between staggered and eclipsed conformations (Delta G double dagger((233 K)) = 44 +/- 1 kJ mol(-1)).
