4-tert-Butyl-2,6-dimethylphenylsulfur Trifluoride Usage And Synthesis

Chemical Properties

White powder

Uses

Air and thermally stable alternative to DAST. Efficient deoxofluorinating agent for a wide variety of substrates.

Uses

Features:

• Tolerance of many functional groups
• Highly selective functionalization
• Highly efficient and broad reaction scope
• Mild reaction conditions

Generally superior reactivity and selectivity to SF₄ and easier and safer to handle.

Shown to promote nucleophilic deoxofluorination reactions and exhibits excellent thermal stability, up to 150 °C, therefore rendering it safely applicable in a variety of processes, including industrial scale production.


Novel fluorinating reagent applicable to a variety of chemical processes (Scheme 1).
