The invention concerns the use as catalyst for transforming carbamates of compounds corresponding to the general formula (I): —Sn (X) (X′) wherein: X′ is selected among chloride, bromide, iodide, thiocyanate radicals, sulphonate radicals, advantageously perfluorinated on the carbon bearing the sulphonate function; X is selected among the values of X′ and among radicals of formula Y-Z; Y is selected among the chalcogen groups, advantageously light (that is oxygen and sulphur); Z is selected in the group consisting of trisubstituted tin, monosubstituted zinc, and the oxygenated acid radicals after ignoring the OH function. The invention is applicable to the coating industry.
该发明涉及将符合通式(I)的化合物用作催化剂,用于转化羰酸酯。其中:X′在氯化物、溴化物、碘化物、硫氰酸根、磺酸根中选择;优选在携带磺酸功能的碳上全氟化的X′;X在X′的值和Y-Z的通式的基团中选择;Y在硫族群中选择,优选轻(即氧和硫);Z在经忽略OH功能后的三取代锡、一取代锌和含氧酸根中选择。该发明适用于涂料行业。
