Dianin's compound

Dianin's compound is 4-p-hydroxyphenyl-2,2,4-trimethylchroman and invented by A.P. Dianin in 1914 [1]. This compound is a condensation isomer of bisphenol A and acetone and of special importance in host-guest chemistry because it can form a large variety of clathrates with suitable guest molecules. One example is the clathrate of Dianin's compound with morpholine [2]. Slow evaporation of a solution containing both organic compounds yields crystals. Each asymmetric unit cell making up the crystal contains 6 chroman molecules of which two are deprotonated and 2 protonated morpholine molecules. The 6 chroman molecules are racemate pairs.
