Claims21
A process for the production of a compound or a mixture of compounds according to general formula (I):
- wherein R1 and R4 are independently selected from the group consisting of H, methyl, Cl and Br;
- R2, R3, R5 and R6 are independently selected from the group consisting of H, methyl, ethyl, propyl and isopropyl;
- and n and m are independently 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 or 10;
- the process comprising a step wherein a compound or a mixture of compounds of general formula (II):
- wherein R1, R4, m and n have the meaning as given above;
- is reacted with water, hydroxide, methanol, methoxide, ethanol, ethoxide, n-propanol, n-propoxide, isopropanol, isopropoxide, or a mixture thereof to obtain the compound or the mixture of compounds of general structure (I);
- or
- comprising a step wherein a compound or a mixture of compounds of general formula (III):
- wherein R1, R2, R3, R4, R5, R6, m and n have the meaning as given above;
- is reacted with bromine, a bromide ion or a bromonium ion, preferably with bromine, to obtain the compound or a mixture of compounds of general structure (I).
