Abstract A process for the direct synthesis of oroganotin chlo- rides of the formula RnSnCl4-n n = 1 - 2 and R being a linear or branched or cycloaliphatic alkyl having 4 to 18 carbon atoms, by reacting tin(II) chloride with alkyl chlorides, characterized in that the reaction is carried out in the presence of amines of the general formula A) R1a N [(CH2CH2O)m CH2CH2OR2]3-a and/or ammonium chlorides of the formula B) R1b N? [(CH2CH2O)m CH2CH2OR2]4-b C1? a = 0, 1 or 2; b = 0, 1, 2 or 3; R1 is a linear or branched or cycloaliphatic alkyl with 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 is H, a linear or branched alkyl with 1 to 20 C at- oms, aryl, substituted aryl or alkyl aryl; and 13 m = 1 - 20 The organotin chlorides produced in this fashion are especially suited as intermediate products for the pro- duction of thermostabilizers for PVC resins.
