摘要:
The invention concerns novel compounds of the formula I ##STR1## The compounds are herbicides and in further embodiments the invention provides: processes for the preparation of compounds of formula I; intermediates useful in the preparation of compounds of formula I; compositions containing as active ingredient compounds of formula I; and processes for severely damaging or killing unwanted plants by applying to the plants or to the growth medium of the plants an effective amount of a compound of formula I.
摘要:
This invention relates to a process for preparing benzoxazines and more particularly 2-substituted-4H-3,1-benzoxazine-4-ones, obtained by reacting at least at about room temperature in the presence of an effective amount of a tertiary amine an isatoic anhydride with an acylating compound consisting of either a carboxylic acid anhydride or an acyl halide.
WHERE R is hydrogen or lower alkyl and rings A and B may be substituted by halogen, nitro, trifluoromethyl, lower alkyl or lower alkoxy. These compounds are useful in preparing the corresponding compounds of the formula
BY SUBJECTING THE FORMER TO DEHYDRATION CONDITIONS TO EFFECT RING-CLOSURE. The latter compounds are useful as tranquilizers, sedatives and hyponotics.
