Unexpected losses in stereochemistry from Stille reactions involving Z-alkenyl halides have been shown to be ligand dependent. A new set of reaction conditions has been developed that, in most cases, leads to highly stereoselective cross-couplings under mild conditions, along with improved yields.
涉及Z-烯基卤化物的Stille反应的立体化学意外损失已显示是配体依赖性的。已开发出一套新的反应条件,在大多数情况下,它们会在温和条件下导致高度立体选择性的交叉偶联,并提高产率。
