    • 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,Y represents an oxygen or sulphur atom,R represents a hydrogen atom and/or alkyl, andR' represents a hydrocarbon group of aliphatic or aromatic character which can contain functional groups,are, for example, valuable intermediates for the production of PVC stabilisers.
    • 在醇的存在下,金属锡与α,β-不饱和腈,氯化氢,溴化氢或碘化氢的直接反应在有机基团中产生具有亚氨酯功能的二有机锡二卤化物。 这种亚氨酯功能可以用硫醇转化成相应的亚氨硫辛酸酯功能。 式“IMAGE”的新型二有机锡二卤化物,其中X表示氯,溴或碘原子,Y表示氧或硫原子,R表示氢原子和/或烷基,R'表示脂族基团的烃基 或可含有官能团的芳族特征,例如是用于生产PVC稳定剂的有价值的中间体。
