Selective clathrate formation with the new host systems cis- and trans-9,10-dihydro-9,10-ethanoanthracene-11,12-dicarboxylic acid: inclusion properties and X-ray structure of an encapsulated acetic acid dimer
Abstract
2 + 4 Cycloaddition of fumaric or maleic acid to anthracene produces the novel host molecules (1) and (2)respectively, which readily form inclusion compounds with a variety of solvents, among which acetic acid, as demonstrated by its crystal structure, give true clathrate formation with encapsulated dimeric guest units.
