摘要: This invention relates to a process for producing alkylphenols by oxidation of alkyl-substituted aromatic aldehydes with hydrogen peroxide in the presence of hydrogen fluoride and hydrolysis thereof. More particularly, under the presence of hydrogen fluoride alkyl substituted aromatic aldehydes are oxidized and converted selectively to aromatic alkyl phenol formates by hydrogen peroxide, without converting to corresponding aromatic carboxylic acid. After the completion of the oxidizing reaction, the produced alkyl phenol formates are hydrolyzed to corresponding alkyl phenols at the time of removing the remaining hydrogen fluoride by distillation.

摘要: A nucleophilic substitution reaction on optionally substituted dihalobenzenes is carried out in the presence of an optional catalyst followed by formation of and subsequent carboxylation of a Grignard reaction intermediate. In particular the present invention provides a process leading to optionally substituted hydroxybenzoic, alkanoyloxybenzoic, formyloxybenzoic and alkoxybenzoic acids from 1-substituted 2,6-dihalobenzenes. The invention also provides a process for the direct formation of an acyl chloride from a Grignard reagent by quenching with phosgene.

摘要: Benzene derivatives of the general formula ##STR1## where Hal is halogen, R.sup.1 is a hydrocarbon radical of 1 to 18 carbon atoms, R.sup.2 is hydrogen or alkyl of 1 to 6 carbon atoms and X is hydrogen or halogen, are prepared by a process in which a toluene derivative of the general formula ##STR2## is electrochemically oxidized in the presence of an acid of the formula R.sup.2 --COOH (III). Novel benzene derivatives of the general formula ##STR3## where R.sup.3 is hydrogen or an R.sup.2 --CO-- radical but R.sup.1 cannot be methyl if X is hydrogen, and of the general formula ##STR4## where R.sup.4 is a branched or cyclic alkyl radical of 3 to 12 carbon atoms, but R.sup.4 cannot be isopropyl if X is hydrogen. The compounds of formulas IV and VI are intermediates for crop protecting agents, e.g. pyrethroids.
