ABSTRACT:
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 ##STR1## wherein X represents a chlorine, bromine or iodine atom,
