Abstract
A process for the preparation of adducts by reacting an alcohol with an epoxy compound in the presence of a catalyst, which comprises reacting an alcohol of formula I ##STR1## wherein A is an aliphatic, cycloaliphatic or araliphatic radical and r is a number from 1 to 10, with a mono- or diepoxide in the equivalent ratio of 1:20 to 20:1, based on the hydroxyl and epoxy groups, in the presence of a metal complex of formula II as catalyst EQU [M.sup.n+ (L.sub.1).sub.x (L.sub.2).sub.y (L.sub.3.sup.m-).sub.z ][X.sup.k- ].sub.(n-zm)/k (II), wherein PA1 M is a metal of the main groups or subgroups of the Periodic Table of the Elements, PA1 L.sub.1 and L.sub.2 are weakly bonded, neutral, unidentale or multidentate ligands, PA1 L.sub.3 is a strongly bonded, non-replaceable neutral or anionic unidentale or multidentate ligand, PA1 X is an anion of the following formulae BF.sub.4.sup.-, PF.sub.6.sup.-, AsF.sub.6.sup.-, SbF.sub.6.sup.-, ClO.sub.4.sup.-, IO.sub.4.sup.-, NO.sub.3.sup.- or is the sulfonate radical of a perfluorinated alkanesulfonic acid, PA1 n is an integer from 1 to 6, PA1 m is 0 or an integer from 1 to 6, PA1 k is 1 or 2, PA1 x is an integer from 1 to 1000, PA1 y is 0 or an in…
