摘要
The new [2]boraferrocenophane derivative [Fe(eta(5)-C(5)H(4))-B(Mes)-B(Mes)-(eta(5)-C(5)H(4))] (2) was prepared by reaction of 1,1'-dilithioferrocene with B(2)(Mes)(2)Cl(2). In addition, the diborane(4) B(2)(NMe(2))(2)Fc(2) (3) was isolated from the reaction of B(2)(NMe(2))(2)Cl(2) and monolithioferrocene. Both species were fully characterized including X-ray diffraction analyses. While B(2)(NMe(2))(2)Fc(2) (3) adopts an unstrained geometry, [2]boraferrocenophane 2 features notable molecular ring strain manifested in the tilt-angle a = 10.5(2)degrees.
