A detailed examination of the preparation, characterisation and reactivity of a range of lead(IV) carboxylates is reported.The replacement of the acetate ligands of lead(IV) tetraacetate by other carboxylates gives the lead(IV) tetracarboxylates 1-16, which have usually been found to be more stable than lead tetraacetate with respect to hydrolysis.These compounds react with allyltributylstannane to give high yields of the corresponding allyl esters 20-34 under mild conditions.

Halomethyl ethers can be prepared from sulfinyl ethers by cleavage of the carbon-sulfur bond with thionyl chloride, acetyl chloride or trimethylsilyl halides.In the presence of alkenyl groups in the substrate, acetyl chloride is the reagent of choice.Trifluoroacetic anhydride reacts in the same manner to form the trifluoroacetoxymethyl ether.With acetic anhydride, catalysis by methanesulfonic acid was required.At elevated temperatures in the presence of sodium acetate the products were formed by the Pummerer rearrangement.
