Case 3-11129/CGM 1-70/1+2/+ Canada ORGANO-TIN COMPOUNDS, PROCESS FOR THEIR PRODUCTION AND USE THEREOF Abstract of the Disclosure The direct reaction of metallic tin with an .alpha.,.beta.-unsaturated nitrile, hydrogen chloride, hydrogen bromide or hydrogen iodide in the presence of an alcohol yields diorgano-tin dihalides with an iminoester function in the organo groups. This iminoester function can be converted with mercaptans into the corresponding iminothioester function. The novel diorgano-tin dihalides of the formula Image wherein X represents a chlorine, bromine or iodine atom, Y represents an oxygen or sulphur atom, R represents a hydrogen atom and/or alkyl, and R' represents a hydrocarbon group of aliphatic or aromatic character which can contain functional groups, are, for example, valuable intermediates for the production of PVC stabilizers.
