    摘要: It is provided a compound of formula (I');

    wherein R 5 is selected from the group consisting of -H, -OM, -COOM, -NH 2 , - SO 3 M, (C 1 -C 4 )alkyl, and halogen; and A is a radical having at least 3 C atoms selected from the group consisting of:
    i) a radical of formula (i)

    wherein R 7 is selected from the group consisting of -OM, and -COOM, and n is 0, 1 or 2; and
    ii) a radical of formula (ii) or of formula (iii)

    wherein R 8 is selected from the group consisting of -H, (C 1 -C 4 )alkyl; and wherein M is independently selected from the group consisting of H, an alkaly metal, and NH 4 + . It is also provided a process for the preparation thereof, a composition comprising it, and its use for correcting deficiencies of metals in plants.
