摘要: Thallous salts of .beta.-dicarbonyl compounds, prepared by reaction of the .beta.-dicarbonyl compounds with a thallous alkoxide, are treated with alkyl halides to give C-alkyl products in high yield, with acyl halides at room temperature to give C-acyl products, and with acyl halides at low temperatures to give O-acyl products. Thallous phenolates are esterified with acyl or aroyl halides. Anhydrides are also prepared, as are biaryls and bi-sec-alkyls. N-Heterocyclics, including purines and pyrimidines, are N-alkylated. Lactams are O-acylated or N-alkylated.

摘要: Substituted anilino-nicotinic acid derivatives are readily prepared from the condensation of two intermediates, 2-alkyl-3-perfluoroalkyl-anilines and alkyl 2-chloronicotinates. The 2-alkyl-3-perfluoroalkyl-aniline intermediate can be prepared via a novel three step synthesis. 3-Perfluoroalkyl-anilines are reacted with an amine directing protecting group reagent to protect the amine. The protected amine is then alkylated, and finally, the directing group is removed to form the 2-alkyl-3-perfluoroalkyl-aniline intermediate. The 2-alkyl-3-perfluoroalkyl-aniline intermediate is condensed with the alkyl 2-chloronicotinate to form the anilino-nicotinic acid derivative.

摘要: A streamline flow of aqueous cobalt (II) sulphate solution passes through a platinum tube which, as an anode, electrolyses the solution to cobalt (III). The flow, with a high surface concentration of nascent cobalt (III), falls into a volume of 1-methylnaphthalene in an organic solvent, and is recovered from underneath for recycling to the platinum tube anode.The cobalt (III) reacts with the 1-methylnaphthalene to form 1-naphthaldehyde. Other oxidations of organic reactants using nascent high-oxidation-state aqueous metal ions are also disclosed.

摘要: Diacetoxyatene compounds are obtained by reacting a perborate such as sodium perborate monohydrate or tetrahydrate and acetic acid with an iodoarene compound under mild conditions, such as 40 to 50.degree. C. The iodoarene can be further substituted by a wide range of substituents, such as halo, nitro, alkyl, alkoxy or carbosylic acid, in any position around the nucleus, except that electron withdrawing substituents occupy meta positions only. The invention process thus enables a wide range of substituted diacetoxyarene compounds to be produced using widely available and easily handled materials under mild operating conditions.
