    Abstract: Special multi-metal cyanide compounds in which at least one of the metals is iron(II) or iron(III) (other than the usual alkali or alkaline earth metal or quaternary ammonium ion) are used as catalysts in a method for the production of hydroxyalkyl esters by reacting carboxylic acids with alkylene oxides. A method for the production of hydroxyalkyl esters of carboxylic acids involves reacting carboxylic acids with alkylene oxides in presence of multi-metal cyanide catalysts of formula (I); M zM a(M (CN)b(A)c)d.fM gXn.mM pYq.h(H2O).eL.kP (I); M = metal ion(s) selected from Zn , Fe , Fe , Co , Ni , Mn , Co , Sn , Pb , Mo , Mo , Al , V , V , Sr , W , W , Cr , Cr , Cd , Hg , Pd , Pt , V , Mg , Ca , Ba and Cu ; M = metal ion(s) selected from Fe , Fe , Co , Co , Mn , Mn , V , V , Cr , Cr , Rh , Ru and Ir , where M and M may be the same or different and at least one of these is Fe or Fe ; M = metal ion(s) selected from Li , Na , K , Rb , Cs , Mg , Ca , Sr and Ba or ammonium ions of formula R R R R N ; R -R = 1-6C hydrocarbyl A, X, Y = halide, hydroxide, sulfate, carbonate, cyanide, thiocyanate, isocyanate, cyanate, carboxylate, oxalate, nitrate, nitrosyl, hydrogen sulfate, phosphate, dihydrogen phosphate, hydrogen phosphate or hydrogen carbonate ions; L = a water-miscible ligand selected from alcohols, aldehydes, ketones, polyethers, esters, polyesters, polycarbonate, ureas, amides, prim., sec. and tert. amines, ligands with pyridine nitrogen, nitriles, sulfides, phosphides, phosphites, phosphanes, phosphonates and phosphates; e, f, k, h, m = 0 or more (fraction or integer); P = an organic additive; a, b, c, d, g, n, p, q, z = numbers compatible with the electroneutrality of (I), where c or z or c and z may be zero.
