1. Phosphorus-containing carboxylic acid derivates of the formula see diagramm : EP0000061,P18,F3 in which R, which may be the same or different, are radicals selected from the group consisting of H, (C1-20 )-alkyl, (C2-8 )-alkyenyl, both radicals being optionally substituted, preferably up to three times, especially once, by halogen, especially chloride or bromine, (C5-6 )-cycloalkyl, phenyl or phen(C1-4 )-alkyl, said radicals being optionally substituted in the ring, preferably up to three times, by halogen, preferably chlorine or bromine, or (C1-4 )-alkyl, an alkali metal or ammonium, preferably sodium or potassium, cation, but R cannot be H or a cation, if the pertinent m, n, p or q is 0, R1 is H, (C1-4 )-alkyl, R2 is CN, COOR4 , CONR5 R6 , CONH2-x (CH2 OH)x , with x being 1 or 2, R3 is H or the group see diagramm : EP0000061,P19,F1 with R'1 and R'2 having the same meaning as R1 and R2 R4 has the meaning given for R, and R5 , R6 is H, (C1-20 )-alkyl or phenyl, both radicals being optionally substituted by halogen, preferably chlorine or bromine, and/or (C1-4 )-alkyl, preferably up to three times, and m, n, p, q independent from each other are 0 or 1, with the restriction that, if R2 is CN or COOR4 , all members of the group m, n, p, q cannot be 1, and that for R = C6 H5 and m = n = p = q = 0, R3 not= H. |
