The invention relates to a compound according to Formula (IX) and salts thereof, wherein R1, R2 and R5 are each independently selected from H and hydrocarbon moieties, which hydrocarbon moieties optionally comprise one or more heteroatoms, and which hydrocarbons optionally comprise substituents, or when the compound according to formula (IX) is a salt, R1 and/or R2 may be a cation, R3, and R4 each independently selected from hydrocarbon moieties, which hydrocarbon moieties optionally comprise one or more heteroatoms, and which hydrocarbons optionally comprise substituents, and wherein any two of R1, R2, R3, R4 and R5 are optionally linked together to form a ring structure. The invention further relates to the preparation of such a compound and to the use of such a compound for preparing a pharmaceutical compound, an agrochemical compound, an intermediate for a pharmaceutical compound or an intermediate for an agrochemical compound.
