Conformational isomerism of 5-isopropyl-1,3-dioxane

Conformational isomerism of trans-[Pt(NH[subscript

X-ray crystallographic analysis of the compound trans-[Pt(NH2C6H11)2I2] revealed the presence of two distinct conformers within one crystal lattice. This compound was studied by variable temperature NMR spectroscopy to investigate the dynamic interconversion between these isomers. The results of this investigation were interpreted using physical (CPK) and computational (molecular mechanics and ...

Isopropyl 3-phenyl­isoxazole-5-carboxyl­ate

In the title compound, C13H13NO3, the isoxazole ring is approximately coplanar with the phenyl ring, the dihedral angle between their planes being 7.37 (19)°. In the crystal, centrosymmetrically related mol-ecules are linked into dimers by pairs of C-H⋯O hydrogen bonds, generating a ring of graph-set motif R 2 (2)(10).

2-Isopropyl-5-methyl­cyclo­hexyl diphenyl­phospho­namidate

In the title compound, C(22)H(30)NO(2)P, the P atom has an irregular tetra-hedral geometry. In the crystal, mol-ecules are connected by N-H⋯O hydrogen-bonding inter-actions, giving rise to a chain along the b axis. The phenyl ring of the anilino group is twisted by 77.40 (16)° relative to the other phenyl ring. The absolute configuration of phospho-rus is S(p).
