Abstract: The invention relates to a method for producing monocarboxy-functionalized dialkylphosphinic acids, esters, and salts, characterized in that a) a phosphinic acid source (I) is reacted with olefins (IV) in the presence of a catalyst A to obtain an alkylphosphonous acid, the salt or ester (II) thereof, and b) the obtained alkylphosphonous acid, the salt or ester (II) thereof is reacted with an oxidizing agent or with an oxidizing agent and water or with oxygen and water in the presence of a catalyst B to obtain the alkylphosphonic acid derivative (III), wherein R1, R2, R3, R4 are identical or different from each other and independently represent, inter alia, H, C1-C18-alkyl, C6-C18-aryl, C6-C18-aralkyl, C6-C18-alkylaryl, X and Y are identical or different from each other and independently represent H, C1-C18-alkyl, C6-C18-aryl, C6-C18-aralkyl, C6-C18-alkylaryl, Mg, Ca, Al, Sb, Sn, Ge, Ti, Fe, Zr, Zn, Ce, Bi, Sr, Mn, Cu, Ni, Li, Na, K and/or a protonated nitrogenous base, and catalysts A and B are transition met

Abstract: The invention relates to a method for producing mono-vinylfunctionalized dialkylphosphinic acids, esters, and salts, characterized in that a) a phosphinic acid source (I) is converted with olefins (IV) to an alkylphosphonic acid, salt, or ester (II) in the presence of a catalyst A, b) the alkylphosphonic acid, salt, or ester (II) thus created is converted with acetylenic compounds of formula (V) into a mono-vinylfunctionalized dialkylphosphinic acid derivative (III) in the presence of a catalyst B, where R1, R2, R3, R4, R5, R6 are the same or different and are independent of each other, among other things, H, C1-C18 alkyl, C6-C18 aryl, C6-C18 aralkyl, C6-C18 alkylaryl, and X stands for H, C1-C18 alkyl, C6-C18 aryl, C6-C18 aralkyl, C6-C18 alkylaryl, Mg, Ca, Al, Sb, Sn, Ge, Ti, Fe, Zr, Zn, Ce, Bi, Sr, Mn, Cu, Ni, Li, Na, K and/or a protonized nitrogen base, and the catalysts A and B are transition metals and/or transition metal compounds and/or catalyst systems comprised of a transition metal and/or a transitio

Abstract: The invention relates to a process for preparing mono-allyl-functionalized dialkylphosphinic acids, esters and salts with allylic compounds, characterized in that a) a phosphinic acid source (I) is reacted with olefins (IV) in the presence of a catalyst A to give an alkylphosphonous acid, or salt or ester thereof (II), b) the alkylphosphonous acid, or salt or ester thereof (II) thus formed is reacted with allylic compounds of the formula (V) in the presence of a catalyst B and of a base to give a mono-allyl-functionalized dialkylphosphinic acid derivative (III), where R1, R2, R3, R4, R5, R6, R7, R8, R9 are the same or different and are each independently, inter alia, H, C1-C18-alkyl, C6-C18-aryl, C6-C18-aralkyl, C6-C18-alkylaryl, and X is H, C1-C18-alkyl, C6-C18-aryl, C6-C18-aralkyl, C6-C18-alkylaryl, Mg, Ca, Al, Sb, Sn, Ge, Ti, Fe, Zr, Zn, Ce, Bi, Sr, Mn, Cu, Ni, Li, Na, K and/or a protonated nitrogen base, and the catalysts A and B are transition metals and/or transition metal compounds and/or catalyst syst
