چکیده
The title compound, C(8)H(17)O(2)PS(2), displays a distorted tetra-hedral geometry around the P atom. The P atom is part of a six-membered ring with an isopropyl group in the equatorial position. The mol-ecules are linked by S-H⋯S hydrogen bonds in the crystal packing.

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 ...

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...
