are readily accessible from carboxylic acids, are utilized as general primary, secondary, and tertiary alkylating reagents for iron‐catalyzed vinylic C−H alkylation of vinyl arenes, dienes, and 1,3‐enynes. This transformation affords olefinic products in up to 98 % yield with high E/Z values. A broad range of functionalities, including carboxyl, boronic acid, methoxy, ester, amino, and halides, are

Polymerization reaction is performed using a polymerizable monomer shown by the following general formula (1) and at least one monomer selected from monomers each having a structure of a salt among a lithium salt, a sodium salt, a potassium salt, and a nitrogen compound salt of a fluorosulfonic acid or the like; then, the structure of the salt of the repeating unit of a polymer obtained by the polymerization reaction is changed to the fluorosulfonic acid or the like by ion exchange. Thus, the present invention provides a polymer compound for a conductive polymer and a method for producing the polymer compound which is suitably used as a dopant for a fuel cell and a conductive material, and which is a copolymer containing a repeating unit of styrene having a 3,3,3-trifluoro-2-hydroxy-2-trifluoromethylisobutyl ether group, and a repeating unit having any of a fluorosulfonic acid, a fluorosulfonimide group, and a n-carbonyl-fluoro-sulfonamide group.

α-Oxo-hydroperoxides have been prepared by the low-temperature base-catalysedautoxidation of methyl isopropyl ketone, di-isopropyl ketone, and 2-methylcyclohexanone. The effect of variations of solvent and base on these autoxidation reactions has been studied. The α-oxo-hydroperoxide structure has been confirmed, and derivatives of both the hydroperoxide and carbonyl functions have been prepared.
