of the disclosure Si, Si'-Diorganyl-N-alkyl-tetrachloro-disilazanes and a process for their preparation The invention relates to a process for the preparation of Si,Si'-diorganyl-N alkyl-tetrachloro-disilazanes of the formula RSiCl2-NR'-SiCl2R, in which R is C1-C4-alkyl, vinyl or phenyl and R' is C1-C4-alkyl, and to these compounds themselves, with the exception of those where R = R' D CH3. To prepare the compounds mentioned, organyltrichlorosilanes RSiCl3 and monoalkylamines R'NH2 are reacted with one another in an aprotic solvent at -10.degree.C to +70.degree.C, the molar ratio of RSiCl3 : R'NH2 being at least 0.3 : 1.
