The oxidation of monoalkylacetylenes using thallium nitrate is a useful method in organic synthesis for converting acetylenic compounds into α-keto carbonyl compounds. In this reaction, a terminal alkyne or monoalkylacetylene undergoes oxidation in the presence of thallium(III) nitrate, which acts as a strong oxidizing agent. The reaction is generally carried out in an aqueous or alcoholic medium, often at room temperature, making it mild compared to other oxidative methods. The transformation is particularly selective for terminal acetylenes, leading to the formation of α-keto aldehydes or
