Sulfur-mediated difunctionalization of internal and terminal alkynes for the synthesis of α-acetoxy ketones
The sulfur-mediated difunctionalization of alkynes is reported to give α-acetoxy ketones in a one-pot operation under mild conditions with 19–92% yield. By using wet potassium acetate as both the aqueous base and nucleophilic reagent, both terminal alkynes and internal alkynes could be converted into the α-acetoxy ketone products.

Synthesis of α-acetoxy and formyloxy ketones by thallium(III) promoted α-oxidation
Treatment of ketones with thallium(III) triflate in amide solvents at 60°C for 30 min followed by addition of small amounts of H2O cleanly provided the corresponding α-acyloxy ketones.

A facile synthesis of secondary α-alkoxy or α-acetoxy aromatic ketones
The treatment of HNIB with aromatic ketones and subsequent solvolysis using alcohol or acetic acid in one-pot system makes it possible to give corresponding secondary α-alkoxy or α-acetoxy ketones in high yields.
