    • Process for preparing one or more iodinated organic substances having a molecular mass of less than 2000 (substances (S)) using (A) at least one free-radical-generating substance chosen from peroxides, diazo compounds, dialkyldiphenylalkanes, substances derived from tetraphenylethane, boranes and iniferter substances comprising at least one thiuram disulphide group, (B) an ethylenically unsaturated substance capable of adding a free radical to its ethylenic double bond, (C) molecular iodine, which comprises the steps according to which at least a fraction of (A), at least a fraction of (B) and at least a fraction of (C) are introduced into a reactor, and then the contents of the reactor are caused to react, while introducing therein the possible remainder of (A), the possible remainder of (B) and the possible remainder of (C), until a moment is reached when the content of the reactor is a mixture comprising one or more substances (S). Iodinated organic substances for whose preparation the abovementioned process is particularly well suited.
    • 使用(A)至少一种选自过氧化物,重氮化合物,二烷基二苯基烷烃的衍生自四苯基乙烷的物质的至少一种自由基产生物质制备一种或多种分子量小于2000的碘化有机物质(物质(S))的方法, 包含至少一种秋兰姆二硫基的硼烷和引发剂物质,(B)能够向其烯属双键加入自由基的烯属不饱和物质,(C)分子碘,其包括以下步骤:至少一部分( A)中,将至少一部分(B)和至少一部分(C)引入反应器中,然后使反应器的内容物反应,同时在其中引入可能的剩余部分(A), 当反应器的含量是包含一种或多种物质(S)的混合物时,直到达到一定时间为止(B)的剩余部分和(C)的可能剩余部分)。 上述方法制备的碘化有机物质特别适合。
