On June 30, 1987, Robert, Dominique; Gawad, Hoda Abdel; Riess, Jean G. published an article.SDS of cas: 2160-93-2 The title of the article was Fluorophosphoranes as Lewis acids. The conditions of access to hexacoordinated neutral adducts via the intramolecular addition of an electron donor. And the article contained the following:
The preparation of bicyclic neutral hexacoordinated fluorophosphorus adducts (I) from RPF4 (R = F, Me, Ph) and (Me3SiOCH2CH2)2X (X = O, S, NH, NMe, NCMe3, NPh) was examined Adduct I was formed predominantly only in the case where R = F and X = S. In all the other cases there was a strong tendency to form ionic species. The 8-membered dialkoxyfluorophosphorane model precursor II (X = CH2) does not form easily, and the driving force towards the formation of the very stable RPF5- anions and of tetracoordinated phosphorylated species leads to its easy decomposition The monocyclic adducts of type III and IV are not easier to prepare: compound V only could be obtained where X = NH2 and R = F, while the spirophosphorane VI was isolated when R = Ph. The experimental process involved the reaction of 2,2′-(tert-Butylazanediyl)diethanol(cas: 2160-93-2).SDS of cas: 2160-93-2
