On April 30, 1994, Houalla, Douraid; Bounja, Zouhair; Skouta, Said; Wolf, Robert; Jaud, Joel published an article.SDS of cas: 2160-93-2 The title of the article was Macrocycles containing bicyclophosphorane moieties. And the article contained the following:
The first stable macrocycles, e.g. I (R = CMe3, Ph), containing pentacovalent phosphorus have been obtained by an Atherton-Todd reaction between the bis(hydridobicyclophosphoranes) with the corresponding binucleophile HO(CH2)2X(CH2)2OH. The tricyclic monophosphoranes II (X = O, NBu, NCMe3, NPh) as well as the noncyclic derivative III have also been isolated. A pathway that accounts for the formation of all these compounds is proposed. The x-ray crystal study of 2 16-membered rings, I (R = CMe3, Ph), confirms the diequatorial placement of the macrocyclic frame on the trigonal bipyramidal phosphorus which retains the most favorable axial-equatorial-axial annelation of the bicyclic moiety. Comparison of these 2 mol. structures points out the effect of the nature of X on the conformation of the macrocycle. The experimental process involved the reaction of 2,2′-(tert-Butylazanediyl)diethanol(cas: 2160-93-2).SDS of cas: 2160-93-2
