Metal complexes with phosphorus chelates - for treating mineral-deficient soils, esp. alkaline soils

摘要

Title complexes are Fe, Mg, Zn, Ca, Cu, Mn, Mo, Co, and Cr chelates with a phosphorus deriv. A-N(B)-C' (where A = hydroxyalkyl or of formula (I) R1 and R2 are H, alkyl, aryl, alkaryl or aralkyl, opt. substd. R3 is alkyl, opt. substd. m is 0 or 1; X is Na, K, NH4 or H ions, P is H or of formula (II) R4 and R5 are hydroxyalkyl; Y is O or S; n is 0 or 1; C' is A, B, H, hydroxyalkyl or -R6-DNE; R6 is alkylene; D and E areas A, B, and C or -CH2-ANC; and when A is hydroxyalkyl B is alkylphosphine and when B is H, A is an alkyl phosphonic gp. and one of R1 and R2 is an o-hydroxy aryl).
