# Ultrafast Solid-Phase Oxidation of Aldehydes to Carboxylic Acids by Atmosphseric Plasma Treatment

## TL;DR

This paper introduces a fast, eco-friendly method to convert aldehydes into carboxylic acids using atmospheric plasma treatment on a solid surface.

## Contribution

A novel, green, and ultrafast oxidation method using atmospheric plasma for aldehydes on solid supports.

## Key findings

- Atmospheric plasma treatment successfully oxidizes aldehydes to carboxylic acids using only air as a reactant.
- The method operates under mild conditions and integrates product isolation into the oxidation process.
- The approach is sustainable and scalable for preparative purposes.

## Abstract

Although atmospheric
plasma treatment is an industrially widespread,
scalable, and environmentally friendly method, it has been generally
used for surface modification, decontamination, or sterilization.
In this paper, a novel, sustainable, green, and ultrafast oxidation
method is described for aldehydes on a preparative thin-layer chromatographic
plate as a solid support. The plasma treatment has proven to be suitable
for producing the corresponding carboxylic acids by using only air
as a reactant source under mild reaction conditions, while the isolation
of the products is also directly integrated into the oxidation process.
Extensibility to other reaction types is not explored yet, but we
are sure that this novel synthesis conception carries a lot of possibilities.
