N, N-disubstituted and N, N, N / N, N, N-trisubstituted thioureas and process for their preparation (II)

摘要

N,N'-disubstituted or N,N,N'- or N,N',N'-trisubstituted thioureas with additional organyloxysilyl function and tertiary amine function of the general formula IMAGE These compounds are prepared as follows: a) Aminoorganylsilanes of the general formula IMAGE are reacted in an organic, inert solvent with carbon disulfide, b) The dithiocarbamates formed thereby having the general formula: IMAGE are isolated and combined with at least the equimolar amount of an amino compound of the general formula H2N-(CH2)n-NR32, this mixture is heated until the reaction is completed and the desired product is subsequently isolated.
