摘要:
Preparation of O-(2-hydroxyalkyl) oximes of formula (I), (R?1 and R2¿ are alkyl or R?1 and R2¿ and the common C atom are 5-membered to 7-membered cycloalkyl; R3 is alkyl) by causing a ketoxime II to react with an olefin oxide III in the presence of a tertiary amine or with a carbonate IV in the presence of a catalyst. The end products (I) are suitable for use as intermediates for crop protection agents.
