- 中文摘要: The o-substituted hybrid phenylphosphines, PPh2(o-C6H4NH2) and PPh2(o-C6H4OH), could be deprotonated with LDA or n-BuLi to yield PPh2(o-C6H4NHLi) and PPh2(o-C6H4OLi), respectively. When added to a solution of (h5-C5H5)Fe(CO)2I at room temperature, these two lithiated reagents produce a chelated neutral complex 1 (h5-C5H5)Fe(CO)[C(O)NH(o-C6H4)PPh2-C,P-h2] for the former and mainly a zwitterionic complex 2, (h5-C5H5)Fe+(CO)2[PPh2(o-C6H4O-)] for the latter. Complex 1 could easily be protonated and then decarbonylated to give 4 [(h5-C5H5)Fe(CO){NH2(o-C6H4)PPh2-N,P-h2}+]. Complexes 1 and 4-I have been crystallographically characterized with X-ray diffraction.
