In this article, we will summarize and compare the reactions of Grignard (RMgX), Gilman (R2CuLi), and organolithium (RLi) reagents. Let’s first see what unites and makes their properties similar or at least creates a pattern for us to predict the … Read more

In the previous post, we talked about Friedel-Crafts alkylation – a classic reaction for attaching alkyl groups to benzene rings. A similar reaction is used for adding an acyl group to the aromatic ring, thus making a ketone. This is … Read more
In the previous post, we talked about the Hofmann Rearrangement, which is the conversion of primary amides to primary amines: Notice that the carbon chain of the product is shorter by one atom because of the decarboxylation that … Read more
Carboxylic acids can be reduced to primary alcohols using an excess of strong reducing agents such as lithium aluminum hydride (LiAlH4 or LAH). As sodium borohydride (NaBH4) is the most common reducing agent we learn about together with … Read more
Preparation of Nitriles Nitriles can be prepared by substitution reactions of alkyl halides with cyanide salts: These are nucleophilic substitution reactions and we introduce the nitrile group by using the nucleophilicity of the cyanide ion. In a similar … Read more
Decarboxylation is the loss of carbon dioxide upon heating, typically characteristic of carboxylic acids with a β-carbonyl group. These are most often beta-keto acids, malonic acid, or its derivatives: Carboxylic acids by themselves are very stable and do … Read more
