    Abstract: The invention relates to a method for producing o-choromethyl benzenecarbonyl chlorides of formula (I), wherein R -R can be the same or different and stand for hydrogen, C1-C4-alkyl, halogen or trifluoromnethyl, by converting benzocondensed lactones of formula (II), wherein R -R have the aforementioned meaning, with gaseous or liquid phosgene and the dimers or trimers thereof. The inventive method is characterized in that the conversion is carried out in the presence of catalytical amounts of a Lewis acid and catalytical amounts of a phosgenation catalyst

    Abstract: The invention relates to a method of preparing 1-alkyl-3-aryl-5-difluoromethoxy-1H-pyrazoles of the formula (I), wherein aryl represents a mono- or polysubstituted phenyl ring, and R 1 represents C 1 -C 4 alkyl. The inventive method is characterized by reacting, in a first reaction step, a beta-ketoester of the general formula (II) with hydrazine and by successively reacting the reaction product obtained with chlorodifluoromethane and a compound R 1 -L, wherein R 1 has the meanings indicated above and L represents the leaving group of a nucleophilic displacement reaction.
