Applications of the bifunctional ferrocenediyl Lewis acid 1,1'-fc{B(CF)} in frustrated Lewis pair (FLP) chemistry are described. The coordination (or otherwise) of a range of sterically encumbered C-, N- and P-centred Lewis bases has been investigated, with lutidine, tetramethylpiperidine, PPh, PBu and the expanded ring carbene 6Dipp being found to be sterically incapable of coordinate bond formation. The chemistry of a range of these FLPs in the presence of HO, NH, CO and cyclohexylisocyanate (CyNCO) has been investigated, with the patterns of reactivity identified including simple coordination chemistry, E-H bond cleavage and C-B insertion.
描述了双功能二茂铁二基路易斯酸1,1'-fc{B(CF)}在受阻路易斯对（FLP）化学中的应用。研究了一系列空间位阻较大的以碳、氮和磷为中心的路易斯碱的配位情况（或其他情况），发现2,6-二甲基吡啶、四甲基哌啶、三苯基膦、三叔丁基膦和扩环卡宾6Dipp在空间上无法形成配位键。研究了一系列这些FLP在水、氨、一氧化碳和环己基异氰酸酯（CyNCO）存在下的化学性质，确定的反应模式包括简单的配位化学、E-H键裂解和C-B插入。
