ABSTRACT:
Organotin compounds having the formula R.sub.3 SnX or R.sub.4 Sn are prepared by reacting metallic zinc with organotin compounds having the formula RSnX.sub.3 or R.sub.2 SnX.sub.2, wherein X stands for chlorine, bromine, iodine or an alkyl carboxylate group having the formula C.sub.p H.sub.2p+l COO, wherein p=1-18, and R represents an organic group.
Satisfactory yields are obtained under mild reaction conditions and without any catalyst being needed if both in the reacting organotin compounds and in the organotin compounds obtained the group R has the structure ##STR1## with A being selected from the group consisting of alkyl having 1-18 carbon atoms, O-alkyl having 1-18 carbon atoms and optionally carrying an alkoxy group having 1-18 carbon atoms, polyoxyalkylene consisting of oxyalkylene groups having 1-4 carbon atoms and carrying as terminal group alkyl or a hydrogen atom, O-cycloalkyl, O-alkenyl having 2-4 carbon atoms, O-phenyl, NH.sub.2 and alkyl substituted amino, and Cl.
