用双（锡1）衍生物1的烯丙基化是高度化学选择性的，并且仅发生在受阻较少的羰基处，如通过二羰基底物11和12的化学选择性烯丙基化所证明的。这种区分两个不同羰基的能力远远上级常规烯丙基化试剂（方案2）。[一51
Allylation with bis (stanny1) derivatives 1 is highly chemoselective, and occurs exclusively at the less hindered carbonyl group, as demonstrated by the chemoselective allylation of dicarbonyl substrates ll and 12. Such ability to discrimate between two different carbonyl groups is far superior to that of conventional allylation agents (Scheme 2).[I 51
