Beschreibung

Allgemeine Beschreibung

Lead(IV) acetate is an inorganic lead salt. It participates in α-acetoxylation of ketones and oxidative decarboxylation of carboxylic acids.[1] It along with an ionic halide (particularly chloride) salt participates in the decarboxylation of acids to afford alkyl chlorides.[2] It affords the corresponding α,β-unsaturated γ-acetoxy-γ-lactones via reaction with 2-(trimethylsiloxy)furans.[3]

Anwendung

Smoothly induces the addition of difluorodiiodomethane to alkenes and alkynes.

Lead(IV) acetate (LTA) may be used as an oxidizing reagent for the oxidation of following compounds:[1]

• unsaturated and aromatic hydrocarbons
• monohydroxylic and saturated alcohols
• nitrogen-containing compounds

It may be used for the following conversions:[1]

• Aromatic primary amines to symmetrical azo compounds.
• Aliphatic primary amines to alkyl cyanides.
• Primary amides to carbamates.
• Hydrazones to azoacetates.
• 2-(Trimethylsiloxy) furans to α,β-unsaturated γ-acetoxy-γ-lactones.[3]
• Aryl ethyl ketones to alkyl 2-arylpropanoates.[4]
• Acetophenones to methyl aryl acetates.[5]
