[3] semicarbazide group. In addition, the reaction could achieve 75% yield of 3 a when the solvent, acetic acid, replaced by higher boiling point and weaker acidic n‐butyric acid (entry 18). Compounds are arbitrarily listed by increasing boiling points unless their melting points are above 40°C. The reaction is useful because semicarbazones, like oximes and 2,4-DNPs, typically have high melting points and crystallize, facilitating purification or identification of reaction products.[2].
