of arylstannanes have been synthesized, through an SRN1 mechanism, in good to excellent yields (74%–99%) by the photostimulated reaction of trimethyl stannyl ion with substrates supporting different nucleofugal groups. The arylstannanes thus obtained were suitable intermediates for Stille cross-coupling reactions leading to asymmetric bi- and triaryl compounds in acceptable global yields. An attractive
通过三甲基锡离子与支持不同核真菌基团的底物的光刺激反应,通过S RN 1机理合成了一系列芳基锡烷,收率好至极好(74%–99%)。如此获得的芳基斯坦酮是用于Stille交叉偶联反应的合适中间体,从而以可接受的总收率产生不对称的双芳基和三芳基化合物。该路线的一个吸引人的特点是,简单的市售苯二醇,氯和甲氧基苯酚可能是有用的起始底物,从而使后者以更少的步骤获得更高的全球产品收率。提出的策略打开了广泛的综合工具。
