    Abstract: The invention relates to a method for producing 1,3-heteroaromatic hydrogen carbonates of formula (IIIa) and/or (IIIb) and/or 1,3-heteroaromatic carbonates of formula (IVa) and/or (IVb). According to the method, 1,3-heteroaromatic 2-carboxylates of formula (Ia) and/or (Ib) or mixtures of 1,3-heteroaromatic 2-carboxylates and 1,3-heteroaromatic alkyl carbonates and/or 1,3-heteroaromatic aryl carbonates of formula (IIa) and/or (IIb), are hydrolysed with water to form 1,3-heteroaromatic hydrogen carbonates and/or 1,3-heteroaromatic carbonates. Said hydrolysis is carried out in the absence of Brønsted acids or Brønsted-bases.
