Rieche reaction
WebIn chemistry, acylation is a broad class of chemical reactions in which an acyl group ( R−C=O) is added to a substrate. The compound providing the acyl group is called the acylating agent. The substrate to be acylated and the product include the following: alcohols, esters amines, amides arenes, ketones WebThe reaction begins (as indicated by evolution of hydrogen chloride) when the first drop of chloro ether is added. After the addition is complete, the mixture is stirred for 5 minutes in …
