The present invention relates to halocarbon and halohydrocarbon chemistry, including methods of dehalogenating halocarbons and halohydrocarbons to provide, inter alia, alcohols, polyols, and epoxides. In general, the methods involve reaction pathways catalyzed by altered hydrolase enzymes that can provide stereoselective or stereospecific reaction products. The invention also includes methods of providing altered nucleic acids that encode altered dehalogenase or other hydrolase enzymes. Additionally, the invention includes various reaction formats and kits.

n-glycols (n = 2-12, 16) bearing two chiral centers were rapidly determined via exciton-coupled circulardichroism (ECCD) using a tris(pentafluorophenyl)porphyrin (TPFP porphyrin) tweezer system in a nonempirical fashion devoid of chemical derivatization. A unique "side-on" approach of the porphyrintweezer relative to the diol guest molecule is suggested as the mode of complexation.
