Abstract
Organotin compounds comprising at least 50% and often at least 90% tetraorganotin compound and the remainder triorganotin halide, which are suitable for conversion to organotin precursors of stabilizers for polymers or fungicides, are made by reacting an alkyl or alkenyl halide with a mixture of tin and zinc (or alloy thereof) with an atomic ratio of at least 0.5:1 zinc to tin, in a liquid comprising an 'onium salt, to produce the organotin compound at least some of which is in the liquid.
