Abstract
New rhodium containing organopolysiloxane-ammonium compounds are described which consist of units of the formula ##STR1## in which R.sup.1, R.sup.2 and R.sup.3 are R.sup.5 --SiO.sub.3/2 (2), R.sup.5 is an alkylene group and the free valences of the oxygen atoms are saturated by silicon atoms of other groups (2), optionally with the insertion of cross-linking agents, R.sup.4 is hydrogen, an alkyl, cycloalkyl or benzyl group, x.sup.n-- is a complex monovalent or polyvalent metal anion of rhodium and chloride, bromide or iodide. Methods for preparing these rhodium-containing organopolysiloxane-ammonium compounds as well as their use as catalysts in reactions with carbon monoxide are also disclosed.
