摘要:
A series of ferrocenylacetylenylbiphenyl derivatives Fc-C C-R [R = C6H4-C6H5 (1), C6H4-C6H4-I (2), C6H4-C6H4-NO2, (3), C6H3(NO2)-C6H4I (4)] and Fc-C C-R'-C C-R" [R" = Fc, R'= C6H4-C6H4 (5), C6H3(NO2)-C6H4 (6); R" = C6H5, R' = C6H4-C6H4 (7)] were synthesized from FcC CH and biphenyl iodides by the Castro-Stephens and Sonogashira coupling reactions, in which compounds 1, 2, 3, 4, 6 and 7 are new. Seven new complexes [Fc-C C-R][Co-2(CO)(6)] [R = C6H4-C6H5 (8), C6H4-C6H4-I (9), C6H4-C6H4-NO2, (10),C6H3(NO2)-C6H4I (11)] and [Fc-C C-R'-C C-R"] [Co-2(CO)(6)](2) [R" Fc, R'= C6H4-C6H4 (12), C6H3(NO2)-C6H4 (13); R" = C6H5, R'= C6H4-C6H4 (14)] were obtained by the reaction of the ligands Fc-C C-R and Fc-C C-R'-C C-R" with Co-2(CO)(8), respectively. Compounds 1-7 and their complexes 8-14 have been characterized by element analysis and spectroscopy, as well as by X-ray diffraction for 1, 4, 8, 9 and 11. The electrochemical data of compounds 1-12 have been obtained by cyclic voltarnmetry. (c) 2007 Elsevier Ltd. All rights reserved.
