PREPARATION OF O-(2-HYDROXYALKYL) OXIMES

摘要

Preparation of O-(2-hydroxyalkyl) oximes of formula (I), (R<1> and R<2> are alkyl or R<1> and R<2> and the common C atom are 5-membered to 7-membered cycloalkyl; R<3> 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.
