IMPROVED PROCESS FOR THE PREPARATION OF PYRETHROIDS

The present disclosure concerns a process for preparing a pyrethroid, said process comprising the steps of: a) reacting an acid chloride with an alcohol in a suitable organic solvent and in the presence of a nitrogen acid acceptor in a temperature range from 0°C to 40°C; and b) washing with water and/or an aqueous basic solution, wherein a suitable amount of a polyamine (W) H2N-(CH2)b-Ae-[(CH2)c-A-]p-(CH2)d-NH2, where A is -NH- or -O-, b and d are independently an integer in the range of 1 -5, c is an integer in the range of 2-5, e is an integer from 0 to 1, p is an integer in the range of 0-5, is added in step a) or b) or after step a) and before step b).
