Dimedone is a cyclic 1,3-diketone. 1,3-Indandione is the cyclic 1,3-diketone fused to a benzene ring. Acetylacetone is prepared industrially by the thermal rearrangement of isopropenylacetate. Another cyclic 1,3-diketone is 2,2,4,4-tetramethylcyclobutanedione, which is a precursor to a useful diol.

Like many alkyldialdehydes, glyoxal is encountered almost exclusively as its hydrate and oligomers thereof. These derivatives often behave equivalently to the See more 1,4-Dialdehydes Succinaldehyde (CH2CHO)2 is the simplest and parent 1,4-dialdehyde. The aromatic derivative is phthalaldehyde. 1,4-Diketones See more Small aldehydes tend to hydrate. Hydration is prevalent for dialdehydes. Glyoxal forms a series of cyclic hydrates. Succinaldehyde hydrates readily to give 2,5-dihydroxytetrahydrofuran. The aromatic phthalaldehyde also forms hydrated. See more WebApr 6, 2024 · AboutTranscript. Ketones are named following IUPAC nomenclature. They are named by finding the carbonyl group and identifying it with a location number, if necessary, then adding the suffix "-one." The common name for ketones is determined by naming the alkyl groups attached to the carbonyl (in alphabetical order), then adding 'ketone'.
