  新的手性全烷基二膦 (S,S)-2,2"-双[(R)-1-(二烷基膦基)乙基]-1,1"-双二茂铁 ((R,R)-(S,S)-烷基TRAPs) 是由 (R)-N,N-二甲基-1-二茂铁基乙胺分四步合成，总产率为 38-68%（MeTRAP：38%，EtTRAP：68%，PrTRAP：53%，BuTRAP：56%，i-BuTRAP： 51%，i-PrTRAP：42%）。烷基TRAP（Et-、Bu-、i-Bu 和i-PrTRAP）与1 摩尔量的PdBr2 反应以良好的产率得到反式-[PdBr2(烷基TRAP)]。这些钯配合物的 X 射线晶体结构表明，无论 P-烷基取代基如何，烷基TRAPs 都以反式螯合方式与钯原子配位。Et-、Bu-和i-PrTRAP的钯配合物的结构几乎具有C2-对称性，但i-BuTRAP的钯配合物显着偏离C2-对称性。烷基陷阱也与 [PtCl2(MeCN)2] 和 [RhCl(CO)2]2
