改变位置：在铂-膦催化剂存在下发生分子内 B(pin)/H 交换，立体选择性地合成有用的顺式-β-甲基取代的烯基硼酸酯（参见方案；B(pin)=4,4,5,5-四甲基-1,3,2-二氧硼杂硼烷-2-基）。
Changing places: Intramolecular B(pin)/H exchange took place in the presence of a platinum–phosphane catalyst, giving synthetically usefulcis‐β‐methyl‐substituted alkenylboronates stereoselectively (see scheme; B(pin)=4,4,5,5‐tetramethyl‐1,3,2‐dioxaborolan‐2‐yl).
