Abstract (en)

[origin: EP1225215A2] New transition metal complexes comprises oxime ligands. Transition metal complexes of formula, M(L)nXm (I) are new. M = Mn, Fe, Co, Ni, Mo or W; L = R1R2C=N-O(H)z; R1 = 1-22C alkyl, 2-22C alkenyl or 5-24C aryl; R2 = H, 1-22C alkyl, 2-22C alkenyl or 5-24C aryl or -C(R1)=N-O(H)z; z = 0 or 1; X = a neutral or anionic ligand selected from pyridines, imidazolines, methylimidazoles, picolines, lutidines, chloride, bromide, nitrate, perchlorate, citrate, hexafluorophosphate and anions of 1-22C organic amines; n = 2-4; and m = 0-4.
