Description
Summary:The title compound, 2-{2-[1,3-di-tert-butyl-4-(tert-butylamino)-2-(tert-butylimino)-1,3,2λ5,4-diazadiphosphetidin-2-yl]-1-(4-methoxyphenyl)prop-2-en-1-yl}-5,5-dimethyl-1,3,2λ5-dioxaphosphinan-2-one, C31H57N4O4P3, was synthesized from the Phospha–Michael addition reaction of cyclodiphosphazane [(t-BuNH)P(μ-Nt-Bu)]2 and allenylphosphonate [(OCH2C(CH3)2CH2O)P(O)C(p-CH3O—C6H4)=C=CH2]. In the crystal, N—H...O and C—H...O hydrogen bonds link the molecules. The structure exhibits pseudosymmetry but attempts to solve it in a higher (monoclinic) space group were unsuccessful.
