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.
Abstract:
The invention relates to a method for producing 1,3-heteroaromatic alkylcarbonates of formula [A] + [R 2 OCO 2 ] - (I), wherein [A] + represents the formula (IIa) or (IIb).
Abstract:
The invention relates to a method which uses magnetic ionic liquids for the liquid-liquid, liquid-solid, or liquid-gas extraction, wherein the partition of the phases occurs in a magnetic field.
