The present invention relates a novel process for preparing a compound of Formula I, The process comprises a novel and inventive step of converting a dione of Formula II into an isatoic anhydride of Formula V in a single step.

Process for preparing anthranilic diamides and intermediates thereof

Novel silylated carboxamides of the formula (I) in which M, L, R, R, R, R and A are as defined in the description,a plurality of processes for preparing these compounds and their use for controlling unwanted microorganisms, and also novel intermediates and their preparation.

Method for controlling phytopathogenic fungi using silylated carboxamides

The invention relates to a method for the thermal decarboxylation of dicarboxylic acids, in particular to 3,4-ethylene dioxythiophene-2,5-dicarboxylic acid as an educt. According to said method the educt is used in solid form and/or the reaction is carried out in the presence of a plurality of fluidised bed bodies. No solvents are used in the reaction and the decarboxylation product that is formed during the reaction is carried away from the reaction zone in gaseous form.
