##STR00001##

In chemical formula 1, A, Ar.sub.2, R.sub.1, R.sub.2, and m are as described in the embodiments.

An object of the present invention is to enable the synthesis of various fluorine-containing compounds having an organic group at both terminals of their tetrafluoroethylene structure (—CF.sub.2—CF.sub.2—). The present invention provides a fluorine-containing complex compound including a fluorine-containing organic metal compound represented by formula (1a):
R.sup.1—CF.sub.2—CF.sub.2-M.sup.1  (1a)
wherein M.sup.1 is a metal selected from the group consisting of copper, zinc, nickel, iron, cobalt, and tin; and R.sup.1 represents an organic group, and at least one ligand selected from the group consisting of pyridine ring-containing compounds and phosphines.

or a pharmaceutically acceptable salt, hydrate, solvate, or prodrug thereof, wherein U, J, V, X, R.sup.1a, R.sup.2b, R.sup.2c, R.sup.5 and t are as described herein. The present invention relates generally to inhibitors of histone deacetylase and to methods of making and using them. These compounds are useful for promoting cognitive function and enhancing learning and memory formation. In addition, these compounds are useful for treating, alleviating, and/or preventing various conditions, including for example, neurological disorders, memory and cognitive function disorders/impairments, extinction learning disorders, fungal diseases and infections, inflammatory diseases, hematological diseases, and neoplastic diseases in humans and animals.

The present invention is directed to reaction mixtures comprising a water-surfactant mixture and a co-solvent. This technology reduced the amount of organic solvents needed for performing chemical reactions. Furthermore, compared to reaction mixtures lacking the co-solvent, solvation of the reactants and products of the chemical reaction is greatly enhanced, leading to a significantly improved yield, purity, reproducibility and robustness.
