Abstract:
1. A method for producing alkylphosphonic acids, esters or salts, comprising the steps of: a) reacting a phosphinic acid source (I) with olefins (IV) in the presence of a catalyst A to form an alkylphosphonous acid, salt or ester (II) b) reacting the alkylphosphonous acid, salt or ester (II) with at least one oxidant or with at least one oxidant and water or in the presence of a catalyst B with oxygen and water to form an alkylphosphonic acid derivative (III) wherein R Mg, Ca, Al, Sb, Sn, Ge, Ti, Fe, Zr, Zn, Ce, Bi, Sr, Mn, Cu, Ni, Li, Na, K a protonated nitrogen base or a combination thereof and the catalysts A and B are transition metals, transition metal compounds, catalyst systems composed of a transition metal, transition metal compound and at least one ligand or a combination thereof and wherein the oxidizing agents are selected from the group of potassium permanganate, manganese oxide, chromium trioxide, potassium dichromate, pyridine dichromate, pyridine chlorochromate, Collins reagent, Jones reagent, Corey-Gilman-Ganem reagent, (Dess-Martin)periodinane, periodoxybenzoic acid, ruthenium tetroxide, ruthenium dioxide, tetra-n-propyl perruthenate, ruthenium trichloride/sodium periodate, ruthenium dioxide/sodium periodate, chlorine, hypochlorite, peracids, peroxo compounds or a combination thereof and wherein the transition metals and transition metal compounds are rhodium, nickel, palladium, platinum, ruthenium, gold or a combination thereof.
