摘要: Phosphonic acid compounds I wherein Eth is optionally substituted 1,2-ethynediyl, ethanediyl or ethene-1,2-diyl; Y1 is oxygen or sulfur; Y2 is oxygen, sulfur or —N(R6)—; Y3 is oxygen, sulfur or —N(R7)—; R1, R2, R6 and R7 are hydrogen or optionally substituted alkyl, alkenyl, alkynyl, cycloalkyl, phenyl or heterocyclyl, or R1 and R2, R1 and R6, R2 and R7 together are optionally substituted 1,2-ethanediyl, 1,3-propylene, tetramethylene, pentamethylene or ethyleneoxyethylene, or R1 and R2 together are optionally substituted 1,2-phenylene; R3 is cyano, halogen, alkyl, haloalkyl, alkoxy or haloalkoxy; R4 is hydrogen or halogen, and R5 is a heterocycle &PHgr;1 to &PHgr;22 as defined in the specification, their manufacture and intermediates therefore. The phosphonic acid compounds are effective against unwanted plants and act as desiccants and defoliants.
