Abstract

Przedmiotem wynalazku jest ulepszony sposób wytwarzania 2,2-dichloro- lub dibromofenylooctanów alkilu o wzorze (I), w którym X oznacza Cl lub Br, n oznacza liczbę całkowitą od 1 do 5, R oznacza atom wodoru, C<sub>1</sub>-C<sub>8</sub> alkil, aryl, heteroaryl, C<sub>1</sub>-C<sub>8</sub>alkoksy, arylooksy lub atom fluorowca i R1 oznacza C<sub>1</sub>-C<sub>8</sub> alkil. Według powyższego sposobu, 2,2-dichloro- lub dibromofenyloacetonitryl o wzorze (II), w roztworze 0,8 do 2 moli wody na mol nitrylu o wzorze (II), poddaje się reakcji z roztworem 1 do 8 moli alkoholu o wzorze R10H (III) na mol nitrylu o wzorze (II) oraz w obecności roztworu 1 do 3 moli HCl lub HBr na mol nitrylu o wzorze (II), ewentualnie w obecności obojętnego, w warunkach reakcji, rozpuszczalnika, z wytworzeniem odpowiednich 2,2-dichloro- lub dibromofenylooctanów alkilu o wzorze (I), przy czym temperatura reakcji w pierwszym etapie wynosiła pomiędzy 30 i 60°C, a w drugim etapie pomiędzy 60 i 100°C. Reakcję prowadzi się jednokrotnie, mieszaninę reakcyjną ochładza się do temperatury pomiędzy 20 i 40°C i rozcieńczono wodą, uzyskując 2,2-dichloro- lub dibromofenylooctan alkilu o wzorze (I).
