Zusammenfassung:PCT No. PCT/EP90/02219 Sec. 371 Date Jun. 17, 1992 Sec. 102(e) Date Jun. 17, 1992 PCT Filed Dec. 17, 1990 PCT Pub. No. WO91/09039 PCT Pub. Date Jun. 27, 1991.The invention relates to a process for the direct synthesis of organotin compounds of the formula RnSnCl4-n wherein n=1-4, and, R=a linear or branched or cycloaliphatic alkyl having 4-18 C atoms, by reacting metallic tin with alkyl chlorides, characterized in that the reaction is carried out in the presence of amines of the general formula A) R1aN [(CH2CH2O)mCH2CH2OR2]3-a and/or ammonium chlorides of the formula B) R1bN [(CH2CH2O)mCH2CH2OR2]4-bCl wherein a=0, 1 or 2; b=0, 1, 2 or 3; R1=linear or branched or cycloaliphatic alkyl having 2 to 24 C atoms, aryl, alkyl aryl or substituted aryl and, if a=2, or b=2 or 3, the R1 groups may be the same or different; R2=H, linear or branched alkyl having 1 to 20 C. atoms, aryl, substituted aryl or alkyl aryl; and m=1-20.
