WebJan 26, 2024 · Cyanohydrins have the structural formula of R 2 C (OH)CN. The “R” on the formula represents an alkyl group, aryl group, or hydrogen. An important feature of cyanohydrin formation is that it requires a basic catalyst. Since hydrogen cyanide itself is a weak acid (pK a = 9.25), the best results occur when a small amount of a strong base ... WebCyanohydrin formation is weakly exothermic, and is favored for aldehydes, and unhindered cyclic and methyl ketones. Two examples of such reactions are shown below. The cyanohydrin from benzaldehyde is … WebCyanohydrins of aldehydes and ketones may be considered as protected forms of the carbonyl compounds.
