摘要： The invention relates to the hydroformylation of olefins or of olefinically unsaturated compounds in the presence of an organic solution which serves as a catalyst and which contains at least one rhodium compound and at least one phosphine-substituted cobalticinium salt. The inventive method is characterised in that phosphine-substituted cobalticinium salts of general formula (I), wherein R1 is the same or varies and is hydrogen or various substituents, are used. An aqueous solution of 1, 1'-bis(diphenylphosphino)-cobalticinium nitrate and a rhodium compound is suitable as a hydroformylation catalyst in a two phase process.

摘要： The invention relates to phosphine-substituted cobalticinium salts of formula (I), wherein R1 is the same or different and is hydrogen, alkyl- or alkoxy radicals with 1 to 14 carbon atoms, also cycloalkyl-, aryl- or aroxy radicals with 6 to 14 carbon atoms, an anellated benzol ring, an acid amide radical -C(O)-NR2R3, wherein R?2 and R3¿ are the same or different and represent hydrogen, alkyl radicals with 1 to 14 carbon atoms, cycloalkyl- or aryl radicals with 6 to 14 carbon atoms, the carboxyl group or an ester radical -C(O)-OR4, wherein R4 represents an alkyl radical with 1 to 14 carbon atoms, also a cycloalkyl- or aryl radical with 6 to 14 carbon atoms; n is the same or different and is a whole number between 0 and 4, m is a whole number between 1 and 3, and X is equal to hexafluoroantimonate, tetraphenyl borate, tosylate, tetrafluoroborate, triflate, trifluoroacetate, triiodide, tribromide, nitrate, perchlorate, sulphate, phosphate, sulphonate O-S(O)¿2?-R?5, R5¿ representing an alkyl radical with 1 to 14 carbon atoms, also a cycloalkyl- or aryl radical with 6 to 14 carbon atoms or carboxylate O-(CO)-R6, R6 representing hydrogen, an alkyl radical with 1 to 14 carbon atoms, a cycloalkyl- or aryl radical with 6 to 14 carbon atoms. The invention also relates to a method for producing the inventive phosphine-substituted cobalticinium salts. These compounds are suitable for use as ligands for metal complexes used as catalysts in chemical processes.
