Abstract
NEW MATERIAL:A 4-cyanobenzooxaphosphorin-2-sulfide (or oxide) shown by formula I (S is O or S; R1 is lower alkyl or lower alkoxyl, lower alkylamino or phenyl; R2 is H, halogen, lower alkyl or lower or lower alkoxyl; n is 0W2).
USE: An insecticide.
PREPARATION: A phosphoric acid chloride (e.g. 0-2-formylphenylethylphos phonothiochloride) shown by formula II is reacted with a cyanide compound (e.g. potassium cyanide) shown by the formula MCN (M is alkali metal) to give a compound shown by formula I. The compound shown by formula II is obtained by reacting a phosphoric acid dichloride shown by formula III with salicylaldehyde shown by formula IV.
