The condensation of organozinc compounds derived from α-bromonitriles with acid anhydrides results in two different types of compounds: either β-ketonitriles {A figure is presented} or cis and trans enol esters {A figure is presented} according to the nature of the initial bromonitrile. Various factors which affect this reaction are being studied. A method of preparation for the above mentioned products is advanced.
Described herein are methods and compounds for extracting water from an aqueous solution. For example, some embodiments include method for extracting water from an aqueous solution, comprising contacting the aqueous solution with a compound comprising one or more carbonyl moieties having an equilibrium constant for a hydration of the carbonyl moiety of at least about 0.5; separating a composition comprising the hydrated compound from the aqueous solution; and reacting the hydrated compound to obtain water.
