| titleOfInvention | Process for the production of methyl-alkyl tin dichlorides |
| abstract | A process for the production of compounds of the formula I CH3(R)SnCl2 (I) wherein R is C4-C20alkyl, which process comprises reacting dimethyl tin dichloride and R-Cl, wherein R has the above meaning, in the presence of a catalyst of the formula II R'(R'')3M(+)X(-)(II) wherein R' is C1-C20alkyl which is unsubstituted or substituted by C1-C4alkoxy, or is C7-C20aralkyl, the aryl moiety of which can be substituted by halogen or C1-C4alkoxy, R'' has the same meaning as assigned to R' or is phenyl which is unsubstituted or substituted by C1-C4alkyl, C1-C4alkoxy or halogen, M(+) is a cation N, P or Sb, and X is an anion selected from the group consisting of chlorine, SnCl3, CH3-SnCl4, (CH3)2SnCl3, SnCl5 or SbCl4. The compounds of the formula I are intermediates for obtaining stabilizers for halogen-containing thermoplastics. |
