| titleOfInvention | Preparation of phenoxyalkyl halides |
| abstract | 1. The method for the preparation of phenoxyalkyl halides of formula 1, in which R is a hydrogen atom, a 2-OCH3, 2-F, 4-F group, X is a chlorine, bromine or iodine atom, and Q is an ethylene -CH2CH2- group, a propylene group -CH2CH2CH2- or the 1-methylethylene group - CH (CH3) CH2- in the reaction of a phenol of formula 2, wherein R is as defined above, with a dihaloalkane Xt-Q-X2, where Xt and X2 are the same or different and are chlorine, bromine or iodine atom, and Q is as defined above, in the presence of a base, characterized in that the reaction is carried out using a dihaloalkane Xt-Q-X2 as a solvent for the reaction mixture, in the presence of solid potassium carbonate or sodium, preferably potassium carbonate, and a crown ether catalyst |
