Research Abstract

(I)DeveIopment of Novel Synthetic Method for the Synthesis of Amines by Aminomethylation of AIkanes Catalyzed by Copper Acetate
Transition metal salts such as copper acetates catalyze the reaction of gaseous alkanes with N,N-dialkylmethylamine N-oxides in trifluoacetic acid (TFA) to afford N,N-dialkylaminomethylated alkanes in good yields. Aminomethylation reaction of propane with trimethylamine N-oxide gave N,N-dimethylisobutylamine as a single regioisomer together with isopropyl trifluoroacetate. Ethane reacts with trimethylamine N-oxide affording N,N-dimethylpropylamine as a sole product From the reaction of methane, methyl trifuoroacetate was obtained cxclusively.
(2)Acetic Acid Synthesis from Methane and Carbon Monoxide by Rare Earth Catalyst System
A new synthetic method of acetic acid in water has been developed from the carboxylation of methane with carbon monoxide using lanthanide catalysts. Ytterbium (III) acetate has been found to be the most active catalyst among the compounds of lanthanide series in the carboxylation reaction of methane with carbon monoxide. Sodium hypochlorite or hydrogen peroxide was used as oxidant in this reaction. Sodium hypochlorite exhibited the favorable activity than hydrogen peroxide in the reaction. The catalytic activity was improved by the addidon of transition metal salts such as manganese (II)acetate. The best result has been found at 0.1 ratio of manganese (II) acetate to ytterbium (III) acetate. The optimum reaction conditions (reaction temperature, 40. C ; time, 20h ; methane, 20atm ; carbon monoxide, 5atm) have been obtained.
