Antistatic compound, surface treatment method for material, and modified material

The present invention provides an antistatic compound. The antistatic compound is obtained by chemically reacting a compound with the structural formula represented by L1' or L2' with a compound Q', and the compound Q' is one or more of a polyhydroxy compound, a polycarboxy compound and a polysulfonate compound; L1' and L2' are shown in the description; and in the formulas L1' and L2', r is 1 or 2, Y is one of a single bond, the oxygen atom, the sulfur atom, the selenium atom, -C(O)-, -SO2-, -NH- and a C1-3 alkylene group, R1 to R10 and R to R are respectively independently selected from the hydrogen atom, a halogen atom, a monovalent polar group and a substituted or unsubstituted monovalent C1-18 hydrocarbon group, and at least one of the R1 to R10 or R to R reacts with the compound Q' to achieve chemical bonding. The antistatic compound can be combined with -CH- group-containing materials such as polyester and nylon to make the materials have antistatic properties and dyeability without reducing the mechanical properties of the materials.

Aerobic Oxidation of 4-Alkyl-N,N-dimethylbenzylamines Catalyzed by N-Hydroxyphthalimide: Protonation-Driven Control over Regioselectivity

A change in regioselectivity has been observed in the hydrogen atom transfer (HAT) reactions from 4-alkyl-N,N-dimethylbenzylamines (alkyl = ethyl, isopropyl, and benzyl) to the phthalimide N-oxyl radical (PINO) by effect of protonation. This result can be rationalized on the basis of an acid-induced deactivation of the C-H bonds α to nitrogen toward HAT to PINO as evidenced by the 104-107-fold decrease in the HAT rate constants in acetonitrile following addition of 0.1 M HClO4. This acid-induced change in regioselectivity has been successfully applied for selective functionalization of the less activated benzylic C-H bonds para to the CH2N(CH3)2 group in the aerobic oxidation of 4-alkyl-N,N-dimethylbenzylamines catalyzed by N-hydroxyphthalimide in acetic acid.

Asymmetric Sommelet-Hauser rearrangement of N-benzylic ammonium salts

(Chemical Equation Presented) [2,3] over [1,2]: The asymmetric Sommelet-Hauser rearrangement of an ammonium salt derived from N-benzylic proline-derived or N-benzylic glycine (-)-8-phenylmenthol ester is shown to proceed with remarkably high levels of stereoselectivity. The method provides unique and efficient access to optically active α-aryl amino acid derivatives.
