- W2026254898 abstract "Abstract L'action de l'acide benzoïque et de l'acide trifluoroacétique sur le bicyclophosphane 1, conduit aux 2 oxo perhydro-1,3,6,2 σ4λ5 dioxazaphosphocines 4a et 4b. L'échange entre les différents conformères de ces 2 cycles à 8 cha[icaron]nons est étudié par RMN à température variable. La structure moléculaire de 4b, determinee par diffraction des rayons-X montre une conformation bateau-chaise compatible avec celle déduite de l'analyze RMN. The reactions of benzoïc and trifluoroacetic acids with the bicyclophosphane 1 lead to the 2-oxo per-hydro-1,3,6,2 σ4λ5 dioxazaphosphorines 4a and 4b. A variable temperature NMR study of the exchange between the conformers of these two eight membered rings is presented. The X-ray molecular structure of 4b shows a boat-chair conformation coherent with that deduced from NMR investigations." @default.
