Hydrocyanation of alkenes

Web2 dagen geleden · Despite efforts to engage aliphatic, unactivated carboxylic acids in this reaction, alkenes were the sole observed products. 11 1-Adamantane carboxylic acid was the one exception to this trend; however, the inability of the adamantyl 3° cation to undergo elimination via geometric constraints represents a special case that is not generalizable.
