  Phosphines containing two N-bound pyrrolidine groups and one alkyl or aryl group have been prepared and shown to be unusually electron rich donor ligands when compared to either tris(N-pyrrolidinyl)phosphine or the trialkyl- or triaryl-phosphines. It is proposed that the electron donating ability of a pyrrolidine group towards phosphorus had been underestimated as only two pyrrolidinyl groups can donate towards the phosphine via the nitrogen lone pair. trans-L2Rh(CO)Cl complexes have been prepared from the phosphines and used to quantify the electron donor characteristics. Two of these complexes have been characterised by X-ray crystallography. The reaction of these phosphines with iron(II) complexes has also been studied. Platinum(II) complexes of the ligands have been prepared and also (in three examples) characterised by X-ray crystallography, which has enabled the steric and bonding properties to be evaluated. tert-Butyl(dipyrrolidinyl)phosphine is one of the most electron rich phosphines known. The dialkyl(pyrrolidinyl)phosphines have been found to contain less potent N→P donation, and are somewhat less good donor ligands.

  含有两个N-键合吡咯啉基团和一个烷基或芳基的磷烷已被制备，并显示出与三(吡咯啉基)磷烷或三烷基或三芳基磷烷相比，具有异常丰富的电子供体特性。提出了吡咯啉基团对磷的电子供给能力可能被低估，因为只有两个吡咯啉基团可以通过氮的孤对电子向磷供给电子。已经从这些磷烷中制备了trans-L2Rh(CO)Cl复合物，并用于量化其电子供体特性。其中两个复合物已通过X射线晶体学进行表征。这些磷烷与铁(II)复合物的反应也已被研究。这些配体的铂(II)复合物已被制备，并在三个例子中通过X射线晶体学进行了表征，从而使得空间位阻和键合特性得以评估。叔丁基(双吡咯啉基)磷烷是已知的最富电子磷烷之一。双烷基(吡咯啉基)磷烷被发现具有较弱的N→P供给能力，因此作为供体配体的性能较差。
