WebbReactions with Specific Functional Groups Using the principles above, we expect KMno 4 to react with alkenes, alkynes, alcohols, aldehydes and aromatic side chains. Examples are provided below. It is easiest to start at the top. Aldehydes Aldehydes RCHO are readily oxidized to carboxylic acids. WebbIn particular, the present contribution deals with the reaction of dimethyl carbonate carried out at high temperatures (140–220 °C), and it will describe the main features of methylation processes as well as some special applications of DMC and higher dialkyl carbonates (dibenzyl carbonate).
