    摘要: Oxadiazines of formula I, wherein R1 is F, Cl or fluoroalkoxy and R2 is alkyl, are prepared by reacting hydrazine derivatives of formula II with a dialkoxymethane in the presence of a protic acid catalyst in an inert solvent under conditions which allow for the prompt removal of the alcohol by-product by distillation. The reaction can be combined with the preparation of the hydrazines derivatives II from the corresponding ketones and hydrazines NH2-NHR3 in the presence of the same protic acid catalyst and an inert solvent. Oxadiazines I are useful as intermediates in the preparation of arthropodicidal agents.
