ABSTRACT:
A process for preparing at least one alicyclic carboxylic acid compound by Grignard reaction, the process comprising:reacting magnesium and at least one alicyclic halide compound in at least one solvent to produce at least one alicyclic Grignard reagent;concurrently adding carbon dioxide to the magnesium, the alicyclic halide compound, the solvent, and the alicyclic Grignard reagent, while the alicyclic Grignard reagent is still being produced, to form at least one alicyclic carboxylate magnesium salt; andhydrolyzing the alicyclic carboxylate magnesium salt to form the alicyclic carboxylic acid compound;wherein the alicyclic Grignard reagent and the alicyclic carboxylate magnesium salt are prepared in a one-pot synthesis.
