A molecular compound represented by the formula ZOSF5, is prepared by combining a reagent represented by the formula Y+ -OSF5 with a substrate represented by the formula ZL, where L is a leaving group, in an organic solvent. Y is either an inorganic cation, in which case a complexing agent is also present, or an organic cation. Z is C1-20 alkyl, aryl, cycloalkyl, combinations thereof, or analogues thereof containing at least one heteroatom. Novel compounds ZOSF5 as can be made using such a process, and novel reactants Y+ -OSF5 used in such a process as well as processes of making the same, are also described.
A method and composition is described for treating impaired neurological function, CNS disease or condition, including altered state of consciousness disorders in a human subject, comprising parenterally administering a composition comprising aminoadamantane derivatives or salts thereof, alone or in combination with other neuroprotective and/or anti-inflammatory compounds, in a pharmacologically effective amount. In some embodiments, a method for treating traumatic brain injury caused by a stroke or an accident in a human subject is provided comprising intravenously administering a composition comprising amantadine hydrochloride in a pharmacologically effective amount to the subject in need thereof.
