Iron(III)-complex (I) is new. Iron(III)-complex of the formula (Fe(L) x(Y) 3-x) (I) is new. L : a ligand of formula (C(O ->)(R1)=C(R2)-C(=O)-N(R3)(R4)) (II); x : 1-3; and Y1 : negatively charged ligand; either R1, R2 = H or a monovalent optionally saturated 1-10C-hydrocarbyl; or R1R2 : divalent 3-6C-alkylene; and either R3, R4 : H or a monovalent saturated 1-12C-hydrocarbyl optionally containing heteroatoms; or R3R4 : a divalent 3-6C-alkylene optionally containing heteroatoms. Independent claims are included for: (1) the preparation of (I); and (2) a two-component polyurethane composition comprising at least one polyol (as a first component), at least one polyisocyanate (as a second component) and (I). |
