Formation of quinhydrone-type complexes composed of quinone dimers and trimers bearing t-butyl and n-dodecyl substituents
Complexation behavior of 5,5-bis(2-methyl-2-propyl)-2,2-bi(1,4-benzoquinone) (1a), 5,5"-bis(2-methyl-2-propyl)-2,2';5',2"-ter(1,4-benzoquinone) (2), and 5,5'didodecyl-2,2'-bi(1,4-benzoquinone) (1b) with hydroquinone was investigated. la and 2 yielded no complex due to the bulkiness of t-butyl substituents, while 1b afforded quinhydrone-type complex, which was revealed to be amorphous by means of X-ray Powder Diffraction (XPD) study.
