Layered basic copper acetate, $Cu(OH)(CH_3COO){cdot}H_2O$ was synthesized. Intercalation compounds of alkyl sulfonates into layered basic copper acetate have been synthesized via anionic exchange. From the X-ray diffraction data and the alkyl sulfonate size, the orientation of the intercalated alkyl sulfonate into layered basic copper acetate was determined.

Water soluble vinyl acetate/alkyl methacrylate copolymers were prepared by the emulsion copolymerization of vinyl acetate and various methacrylates such as methyl methacrylate (MMA) and ethyl methacrylate (EMA). Potassium persulfate (KPS) and ammonium persulfate (APS) were used as an initiator. Poly (vinyl alcohol) (PVA) was used as a protective colloid. The drying characteristics of the prepared poly(vinyl acetate-co-methyl methacrylate) (PVAc/PMMA), poly(vinyl acetate-co-ethyl methacrylate) (PVAc/PEMA) were studied using moisture meter at the temperature between 100 and $200^{\circ}C$. The significant results are described as follows. The activation energy of the isothermal drying process of the copolymers has the order of PVAc/PMMA> PVAc/PEMA> PVAc.

Vinyl acetate/alkyl acrylate copolymers were prepared by water-born emulsion copolymerization according to the compositional change of vinyl acetate and various alkyl acrylates such as methyl acrylate (MA), ethyl acrylate (EA), and n-butyl acrylate (BA). Ammonium persulfate (APS) was used as an initiator and poly(vinyl alcohol) (PVA) was used as a protective colloid. The significant result was described as follows. The activation energy determined by an isothermal analysis in the temperature region between $100{\sim}200^{\circ}C$ of the copolymer had the order of PVAc/PMA > PVAc/PEA > PVAc/PBA. The peel strengths before and after the plasma treatment were the order of PVAc/PMA > PVAc/PEA > PVAc/PBA.

The effects of his ($\beta$-amino-ethyl-oxo) oxalate and bis ($\alpha$-amino-methyl-oxo) oxalate on the toxicity of lead acetate in rast were examined. Rats were given intraperitoneally at the dose of lead acetate 45 mg/kg. The exposure of lead acetate showed the 70% decrease of ALAD ($\delta$-amino levulinic acid dehydratase) activity in red blood cell. In vivo 122 mg/kg administration of bis ($\beta$-amino-ethyl-oxo) oxalate and bis ($\alpha$-amino-methyl-oxo) oxalate showed the 50% increase of ALAD activity, whereas 149 mg/kg administeration of Ca-EDTA had no effect. In vitro, the same results were obtained. Both compounds had hemolytic activity at concentrations higher than that required for showing the 50% ALAD activity increase in vivo.

Acrylamide, N-alkyl substituted acrylamides and N,N-diethylacrylamide were reacted with aryl bromides in the presence of triethylamine and palladium acetate-triorthotolyl phosphine catalyst to form the various substituted aryl conjugated enamides. These reactions proceeded selectively and (E)-isomer of aryl conjugated enamides was obtained. N-alkyl substituted acrylamides were more reactive than acrylamide or N,N-diethylacrylamide and gave high yields of vinylated products. Aryl bromides with electron withdrawing group showed good reactivity but aryl bromides with electron donating group showed poor reactivity or no reactivity for acrylamide or N,N-diethylacrylamide.

In the emulsion polymerization of vinyl acetate with Triton-X(Alkyl-aryl-polyether alcohol) and polyvinyl alcohol as emulsifier, some relations between the conditions of polymerization and the polymerization rate, polymerization degree and stability of the emulsion are studied and discussed.

5-Alkyl-2(3H)-benzofuranones(3a-e) were prepared from Friedel-Crafts reaction of 4-alkylphenols with methyl 2-chloro-2-(methylthio)acetae(1) followed by the treatment of zinc du st-acetic acid. The reaction of disubstituted phenols with 1 in the presence of stannic chloride afforded 3-methyltWa-2(3H)-benzofuranone derivatives(11a-c), which were readily converted into 2(3H)-benzofuranone derivatives(12a-c) by desulfurization with zinc dust-acetic acid.

A new polynuclear complex of manganese stearate has been prepared by substitution of acetate with stearic acid. The stearate ion with long alkyl chain was used to isolate molecular $Mn_{12}$ cluster from each other. The $Mn_{12}$-stearate compound prepared is soluble in most organic solvents and resistant against water catalyzed reduction. The $Mn_{12}$-stearate compound shows similar electrochemical, magnetic properties to the pristine $Mn_{12}$-acetate.

Numerous psychotropic and addictive substances possess structural features similar to those of β-phenethylamine (β-PEA). In this study, we selected 29 β-PEA derivatives and determined their structure-activity relationship (SAR) to their ability to inhibit dopamine (DA) reuptake; conducted docking simulation for two selected compounds; and identified their potential functionals. The compounds were subdivided into arylethylamines, 2-(alkyl amino)-1-arylalkan-1-one derivatives and alkyl 2-phenyl-2-(piperidin-2-yl)acetate derivatives. An aromatic group, alkyl group, and alkylamine derivative were attached to the arylethylamine and 2-(alkyl amino)-1-arylalkan-1-one derivatives. The inhibitory effect of the compounds on dopamine reuptake increased in the order of the compounds substituted with phenyl, thiophenyl, and substituted phenyl groups in the aromatic position; compounds with longer alkyl groups and smaller ring-sized compounds at the alkylamine position showed stronger inhibitory activities. Docking simulation conducted for two compounds, 9 and 28, showed that the (S)-form of compound 9 was more stable than the (R)-form, with a good fit into the binding site covered by helices 1, 3, and 6 of human dopamine transporter (hDAT). In contrast, the (R, S)-configuration of compound 28 was more stable than that of other isomers and was firmly placed in the binding pocket of DAT bound to DA. DA-induced endocytosis of dopamine D₂ receptors was inhibited when they were co-expressed with DAT, which lowered extracellular DA levels, and uninhibited when they were pretreated with compound 9 or 28. In summary, this study revealed critical structural features responsible for the inhibition of DA reuptake and the functional role of DA reuptake inhibitors in regulating D₂ receptor function.
