Nucleophilic Activation of Carbon Monoxide: Applications to Homogeneous Catalysis by Metal Carbonyls of the Water Gas Shift and Related Reactions

摘要: Publisher Summary This chapter discusses the roles played by certain nucleophile adducts of metal–coordinated carbon monoxide in stoichiometric and catalytic chemistry metal–carbonyl complexes relatively recent developments for systems where oxygen or nitrogen bases have been used as nucleophiles. The syntheses, spectral characterizations, chemical reaction studies various nucleophile–carbonyl are described with goal drawing attention to how such adduct formation not only activates carbonyl directly involved further but also influences reactivities balance complex. Preparation direct addition a anion Nu – coordinated CO has widely applicable approach. Nuclear magnetic resonance (especially 13 C NMR) infrared spectroscopy proved most successful diagnostic tools characterizing transformations L n M–(CO)Nu related species. Reactions uncharged nucleophiles provide different situation. Kinetics which characterizable nucleophilecarbonyl isolated few.
