Chlorosulfites prepared in situ using thionyl chloride react with nitrile complexes of titanium (IV) fluoride to give a one-pot conversion of alcohols into amides. For the first time, amides are obtained from cyclic alcohols with stereoretention. Critical to the design of these new Ti(IV) reactions has been the use of little explored Ti(IV) nitrile complexes which are thought to chelate chlorosulfites
使用亚硫酰氯原位制备的亚硫酸盐与氟化钛 (IV) 的腈络合物反应,将醇一锅法转化为酰胺。首次从具有立体保留的环醇中获得酰胺。设计这些新的 Ti(IV) 反应的关键是使用很少探索的 Ti(IV) 腈配合物,这些配合物被认为可以螯合过渡态的氯亚硫酸盐以产生碳正离子,该碳正离子可通过前缘快速被腈亲核试剂捕获侧攻击机制。
