Reaction of [(μ-RE)(μ-CO)Fe2(CO)6]− (E=S, Se) with N2CHCO2Me. Synthesis and characterisation of (μ-RE)[μ-η2-NNCH(R′)CO2Me]Fe2(CO)6 and (μ-PhSe)[μ-η1-NNCH(Me)CO2Me]Fe2(CO)6
摘要:
Reaction of [M][(mu-RE)(mu-CO)Fe-2(CO)(6)] (E = S, Se; M = Et3NH, Na) with N2CHCO2Me give the intermediate [M][(mu-RE)(mu-N2CHCO2Me)Fe-2(CO)(6)] Action of LI with counterion Et3NH+ yields neutral complexes (mu-RE)(mu-eta(2-)N=NCH2CO2Me)Fe-2(CO)(6) (1, RE=Bu'S; 2, RE=PhS; 3, RE=PhSe). Treatment of II (M=Na) with Mel affords (mu-RE)[mu-eta(2)-N=NCH(Me)CO2Me]Fe-2(CO)(6) (4, RE = Bu'S; 5, RE = PhS). In the case of RE = PhSe, the reaction of II with Mel gives two isomers, (mu-PhSe)[mu-eta 2-N=NCH(Me)CO2Me]Fe-2(CO)(6) (6) and (mu-PhSe)[mu-eta(1)-N=NCH(Me)CO2Me]Fe-2(CO)(6) (7). The structure of complex 7 has been determined by single-crystal X-ray diffraction technique. (C) 2000 Elsevier Science S.A. All rights reserved.
