We report in this paper the preparation and use of stannanes 11, 12a, and 12b, compounds whose 3-pyrenylpropyl side chain affinity for activated carbon simplifies tin removal and product isolation. Our pyrene-supported reagents can be used for radical reductions and cyclizations (11), radical and cationic allylations (12a), and Stille couplings (12b) in much the same way as tributyltin derivatives
我们在本文报道的制备和使用锡烷的11,图12A,和12B,化合物,其3- pyrenylpropyl侧链亲和力活性炭简化锡去除和产物分离。我们的pyr支持的试剂可用于自由基还原和环化(11),自由基和阳离子烯丙基化(12a)以及Stille偶联(12b),其方式与三丁基锡衍生物大致相同。
