Synthesis, molecular structure and reactivity of new π-conjugated diyne with ferrocenyl and phenyl units
摘要:
New pi-conjugated butadiynyl ligand FcC(CH3)(2)Fc'-C=C-C=C-Ph (L-1) has been synthesized and its reaction with Co-2(CO)(8) has been studied. New clusters [FcC(CH3)(2)Fc'-C=C-C=C-Ph][(Co-2(CO)(6)](n) [(1): n = 1; (2): n = 2] and [Fc-C=C-C=C-Ph][Co-2(CO)(6)](n) [(3): n = 1; (4): n = 2] were obtained by the reaction of ligands FcC(CH3)(2)Fc'-C=C-C=C-Ph (L-1) and Fc-C=C-C=C-Ph (L-2) with Co-2(CO)(8) respectively and the composition and structure of the clusters and ligands have been characterized by elemental analysis, FTIR, H-1 and C-13 NMR and MS. The crystal structures of compounds L-1, L-2, 2 and 4 have been determined by X-ray single crystal analysis. (c) 2006 Elsevier Ltd. All rights reserved.
