Reactions of organometallic complexes with carbon monoxide. Part II. Reactions of phenyl compounds of iodine(III), lead(IV), and thallium(III)

Abstract

The reactions of PhPb(OAc)₃ and of compounds of the type lPh₂X and TlPhX₂(X = Cl, NO₃, or RCO₂) with carbon monoxide have been studied. Methyl benzoate and benzoic acid are formed in methanol solution, and also some methyl benzoylformate was obtained from lPh₂OAc. Only the thallium compounds react in benzene solution, the main product being thallium(I) benzoate. For lPh₂NO₃ and TlPhCl₂, a comparison between the reactivity towards carbon monoxide and triphenylphosphine has been made, and the complexes TlPhCl₂(PPh₃) has been characterised.
