Process for preparing amino-oxo-acetate-functional organosiloxanes by reacting silanes of the general formula with siloxanes selected from linear siloxanes of the general formula HO[SiR 2 O] t H and cyclic compounds of the general formula (SiR 4 2 O) s, where R can be identical or different and denotes a hydrogen atom or monovalent, optionally substituted, SiC-bonded hydrocarbon radicals which can be interrupted by heteroatoms, preferably an oxygen atom, R 1 can be identical or different and denotes monovalent, optionally substituted, SiC-bonded hydrocarbon radicals which can be interrupted by heteroatoms, preferably an oxygen atom, Y can be identical or different and represents divalent, optionally substituted hydrocarbon radicals which can be interrupted by oxygen atoms, R 2 can be identical or different and denotes a hydrogen atom, monovalent, optionally substituted hydrocarbon radicals which can be interrupted by oxygen atoms, R 3 can be identical or different and denotes monovalent, optionally substituted hydrocarbon radicals which can be interrupted by oxygen atoms, R 4 can be identical or different and denotes a hydrogen atom, a Si-bonded halogen atom, a Si-bonded hydroxy group or monovalent, optionally substituted, SiC-bonded hydrocarbon radicals which can be interrupted by heteroatoms, preferably an oxygen atom, R X can be identical or different and denotes a hydrogen atom or optionally substituted hydrocarbon radicals, n is 0, 1 or 2, s is an integer from 3 to 10 and t is an integer greater than 1, in the presence of catalysts. silanes of the general
