Novel condensation products of diketene was written by Marcus, E.;Chan, John K.. And the article was included in Journal of Organic Chemistry in 1967.COA of Formula: C9H10O3 This article mentions the following:
A study of some self-condensation products of diketene was undertaken. In addition to dehydroacetic acid (I), 3,9-diacetyl-4,5,10-trimethyl-2H,8H-benzo[1,2-b:3,4-b’]dipyran-2,8-dione (II), 3,6-diacetyl-4,7-dimethyl-5-hydroxycoumarin (III), and 3,8-diacetyl-4,7-dimethyl-5-hydroxycoumarin (IV) were identified as condensation products of diketene. Support for these proposed structures was obtained by degradations, rearrangements, independent syntheses, and spectral data. A mechanism that rationalizes the formation of II, III, and IV is suggested. A newly discovered reaction by which II, III, and IV can be made directly from diketene in 26, 13, and 10% yields, resp., is also reported. 12 references. In the experiment, the researchers used many compounds, for example, 2′,6′-Dihydroxy-4′-methylacetophenone (cas: 1634-34-0COA of Formula: C9H10O3).
2′,6′-Dihydroxy-4′-methylacetophenone (cas: 1634-34-0) belongs to alcohols. Because alcohols are easily synthesized and easily transformed into other compounds, they serve as important intermediates in organic synthesis. The most common reactions of alcohols can be classified as oxidation, dehydration, substitution, esterification, and reactions of alkoxides.COA of Formula: C9H10O3
