A highly regio- and stereoselective diboration of allenes was achieved with a catalytic amount of phosphine-free Pd complex and alkenyl or aryl iodide.
双硼试剂加成到1，2双烯的反应，传统上利用Pt金属错合物为催化剂，根据文献的报导，单独只使用Pd金属错合物是无法进行此反应的。

First, when operating the DABCO-catalyzed Ireland-Claisen rearrangement of propargylic acrylates 18b-d, we added dienophiles 40a-f in the reaction system to capture the rearranged allenes products respectively. The Diels-Alder adducts 41a-i were obtained with complete regioselectivity. Thus a novel tandem Ireland-Claisen rearrangement /Diels-Alder reaction process with propargylic acrylates has been developed.
首先在进行DABCO-催化的丙烯酸炔丙酯类化合物18b-d的Ireland-Claisen重排反应的同时，于反应体系中分别加入亲二烯体40a-f捕获重排得到的连二烯中间体，一步反应获得了单一区域选择性的Diels-Alder环加成产物41a-i，从而创建了一条新颖的丙烯酸炔丙酯类化合物的Ireland-Claisen重排与Diels-Alder环加成的串联反应路线。
