Unsaturated Dimetal Cyclopentadienyl Carbonyl Complexes

摘要: Publisher Summary This chapter distinguishes complexes X* with Cp* ligands from the corresponding Cp X by an asterisk. The differing electronic and steric requirements of can have dramatic effects on reactivity at metal atom to which they are bound. ability isolate compounds is sometimes affected. helps explain reason for permethyl derivatives CP * 2 M (μ – CO) 4* 5* being well known while cyclopentadienyl analogs 4 5 scarcely reported. It reviews that one useful physical effect group greater solubility generally displayed as compared their analogs. However, differences in chemistry often demonstrated may or not be considered desirable. Enhanced relative also achieved using Cp' (C H Me) ligand. While species higher than compounds, unaffected single methyl substituent.
