一系列烯胺与Piers的硼烷HB(C6F5)(2)进行反Markovnikov氢化反应，得到C-2桥联的受挫N/B Lewis对，具有弱的N中心点B相互作用。一些例子显示了典型的受挫Lewis对与二氢或1-炔烃的反应。其中一种N/B FLP用作烯胺加氢的活性催化剂。用X-射线衍射法对许多新化合物进行了表征。
A series of enamines undergoes anti-Markovnikov hydroboration with Piers' borane HB(C6F5)(2) to yield C-2-bridged frustrated N/B Lewis pairs, featuring weak N center dot center dot center dot B interaction. Some examples show typical frustrated Lewis pair reactions with dihydrogen or with 1-alkynes. One such N/B FLP serves as an active catalyst for the hydrogenation of enamines. Many of the new compounds were characterized by X-ray diffraction.
