Rhodium-containing organopolysiloxane-ammonium compounds, methods for their preparation and use

摘要

New rhodium containing organopolysiloxane-ammonium compounds are described which consist of units of the formula <IMAGE> (1) in which R1, R2 and R3 are R5-SiO3/2 (2), R5 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, R4 is hydrogen, an alkyl, cycloalkyl or benzyl group, xn- 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.
