ABSTRACT:
A process of preparing organostannic trihalides by reaction of an olefin compound activated by a carbonyl group adjacent to the double bond, in the presence of a hydrohalic acid, with a stannous compound in a solvent-free medium and an excess of olefin which is at least 0.5 mol per mol of stannous compound.
Trihalides are obtained by this process; these trihalides may be converted into organostannic compounds for stabilizing compositions for halovinyl resins.
