Rotary biomol. machines rely on highly sym. supramol. structures with rotating units that operate within a densely packed frame of reference, stator, embedded within relatively rigid membranes. The most notable examples are the enzyme FoF1 ATP synthase and the bacterial flagellum, which undergo rotation in steps determined by the symmetries of their rotators and rotating units. Speculating that a precise control of rotational dynamics in rigid environments will be essential for the development of artificial mol. machines, we analyzed the relation between rotational symmetry order and equilibrium rotational dynamics in a set of crystalline mol. gyroscopes with rotators having axial symmetry that ranges from two- to fivefold. The site exchange frequency for these mols. in their closely related crystals at ambient temperature varies by several orders of magnitude, up to ca. 4.46 × 108 s-1. This study involved multiple reactions and reactants, such as Cubane-1,4-diyldimethanol (cas: 60462-27-3Application In Synthesis of Cubane-1,4-diyldimethanol).
Cubane-1,4-diyldimethanol (cas: 60462-27-3) belongs to alcohols. A strong base can deprotonate an alcohol to yield an alkoxide ion (R―O−). For example, sodamide (NaNH2), a very strong base, abstracts the hydrogen atom of an alcohol. The most common reactions of alcohols can be classified as oxidation, dehydration, substitution, esterification, and reactions of alkoxides.Application In Synthesis of Cubane-1,4-diyldimethanol
