The title compound, C(15)H(17)O(6)P, was obtained from a reaction of 4-methyl-7-hy-droxy-coumarin and 2-chloro-5,5-dimethyl-1,3,2-dioxaphosphinane 2-oxide. There are two mol-ecules in the asymmetric unit in which the benzopyran ring system is almost planar [r.m.s. deviation for each molecule = 0.003 Å]. In the crystal, C-H⋯O hydrogen bonds and π-π stacking inter-actions [with centroid-centroid ...

In the title compound, C(25)H(32)O(7), the 3-hy-droxy-5,5-dimethyl-cyclo-hex-2-enone rings adopt slightly distorted envelope conformations with the two planes at the base of the envelope forming dihedral angles of 57.6 (4) and 53.9 (9)° with the benzene ring. There is an intra-molecular hy-droxy-ketone O-H⋯O inter-action between the two substituted cyclo-hexane rings as well as a short intra-mo...
متن کاملSynthesis and structural investigation of N-acyl selenophosphoramides.
2-Amino-2-seleno-5,5-dimethyl-1,3,2-dioxaphosphorinane reacts with acyl chlorides (4-chlorobenzoyl chloride or pivaloyl chloride) yielding the respective N-acyl selenophosphoramides. These derivatives do not isomerise to the related selenocarbonyl imides. X-ray study of N-(4-chlorobenzoyl)-2-amino-2-seleno-5,5-dimethyl-1,3,2-dioxaphosphorinane indicates that the selenium atom is placed in the e...
