The title compound, 2-{2-[1,3-di-tert-butyl-4-(tert-butyl-amino)-2-(tert-butyl-imino)-1,3,2λ(5),4-diaza-diphosphetidin-2-yl]-1-(4-meth-oxy-phen-yl)prop-2-en-1-yl}-5,5-dimethyl-1,3,2λ(5)-dioxaphosphinan-2-one, C(31)H(57)N(4)O(4)P(3), was synthesized from the Phospha-Michael addition reaction of cyclo-diphos-pha-zane (t-BuNH)P(μ-Nt-Bu) and allenyl-phospho-nate [(OCH(2)C(CH(3))(2)CH(2)O)P(O)C(p-CH(3)O-C(6)H(4))=C=CH(2)]. In the crystal, N-H⋯O and C-H⋯O hydrogen bonds link the mol-ecules. The structure exhibits pseudosymmetry but attempts to solve it in a higher (monoclinic) space group were unsuccessful.
