At present adamantane, the only diamondoid, has attracted a lot consideration, as a result of its distinctive construction and properties for the development of nanostructured entities. 1,1′-biadamantane is an almost inflexible hydrocarbon shaped from the covalent attachment of the 2 adamantane models. On this research, adamantane was first transformed to 1,1′-biadamantane, and the obtained 1,1′-biadamantane was brominated to offer its hexabromo by-product. The six bromine atoms within the hexabromo by-product have been then substituted by six phenols through a Friedel-Crafts alkylation response to yield the novel hexakis (4-hydroxyphenyl) by-product. Additionally, hydrolysis of the heaxabromo by-product afforded the novel hexahydroxy by-product.
