# From perfluoroalkyl aryl sulfoxides to ortho thioethers

## TL;DR

A new method was developed to create ortho thioether derivatives using a [3,3]-rearrangement from perfluoroalkyl aryl sulfoxides.

## Contribution

The paper introduces a one-pot two-step protocol for synthesizing original ortho thioether derivatives.

## Key findings

- A [3,3]-rearrangement enabled the synthesis of aryl-SCF3 compounds.
- Variation of nitriles and trifluoroalkyl sulfoxides produced diverse aryl-SCF3 derivatives.
- Modifications to the perfluoroalkyl chain were successfully achieved.

## Abstract

Access to original ortho thioether derivatives was achieved through a [3,3]-rearrangement in a one-pot two-step protocol. Several aryl-SCF3 compounds are reported by variation of the nitrile or of the trifluoroalkyl sulfoxide starting material. The variation of the perfluoroalkyl chain was also possible.
