Title:

PHOSPHONATE GROUP-CONTAINING HERBICIDE AND MANUFACTURE OF INTERMEDIATE FROM BENZOXAZINE

Document Type and Number:

Japanese Patent JPS61215399

Kind Code:

A

Abstract:

Preparation of intermediates for herbicides of formula (I) by the reaction of organic phosphites with benzoxazines of formula Bzx-CH2-CO-Y (II) in which Bzx denotes the radical of formula: X is a usual substituent of phenols n is an integer from 0 to 4 R1 and R2 are H or such that OR1 and OR2 are hydrolyzable Y is -OM or -NR3R4 M is H or is such that COOM is a salt or an ester R3 and R4 are H or a hydrocarbon radical, and one of them can be R5-SO2-, and R5 is a hydrocarbon radical, substiuted if appropriate. Products obtained by the process and their use as herbicides.
