설명

일반 설명

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

애플리케이션

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

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

It may be used for the following conversions:

• 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.
• Aryl ethyl ketones to alkyl 2-arylpropanoates.
• Acetophenones to methyl aryl acetates.

Smoothly induces the addition of difluorodiiodomethane to alkenes and alkynes.
