A four-membered cyclic compound containing two carbonyl groups, commonly used in organic chemistry and pharmaceutical synthesis.
From 'di-' (two) + 'ketene' (a two-atom carbon-oxygen functional group), creating a descriptive chemical name for this molecule's structure. The term emerged in early 20th-century organic chemistry.
Diketene looks simple—just a tiny four-membered ring—but it's one of the most useful building blocks in pharmaceutical chemistry. It's like discovering that a simple LEGO brick can build almost anything!
