Web18 apr. 2024 · Alkanes are the simplest organic compounds made up of carbon and hydrogen only. They have the general formula CnH2n+2. Skip to content. ... The iodination reaction of an alkane is a reversible one as the hydrogen iodide formed during the reaction is a highly reducing agent which reduces the alkyl iodides to the alkanes. WebAlkenes as Substrates ... [28,29] and α-iodination of carbonyl compounds; however, these were very specific and only involved pathways towards a very limited range of α-haloketones. In 2024, Verkariya and co-workers reviewed the synthetic access to α-iodocarbonyl compounds .
