    摘要: The invention relates to a process for the direct synthesis of organotin compounds of the formulaR.sub.n SnCl.sub.4-nwhereinn=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 formulaA) R.sup.1.sub.a N [(CH.sub.2 CH.sub.2 O).sub.m CH.sub.2 CH.sub.2 OR.sup.2 ].sub.3-a and/or ammonium chlorides of the formulaB) R.sup.1.sub.b N [(CH.sub.2 CH.sub.2 O).sub.m CH.sub.2 CH.sub.2 OR.sup.2 ].sub.4-b.sup.Clwhereina=0, 1 or 2;b=0, 1, 2 or 3;R.sup.1 =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 R.sup.1 groups may be the same or different;R.sup.2 =H, linear or branched alkyl having 1 to 20 C. atoms, aryl, substituted aryl or alkyl aryl; andm=1-20.
