A couple of novel triptycene-derived calix[6]arenes with fixed conformations were synthesized, and shown to form tubular assemblies with aromatic rings as the walls and phenolic hydroxyl groups situated in the cavities, in the solid state. [ABSTRACT FROM AUTHOR]

The title compound, C13H10N2SCl2 was prepared by the reaction of p-chloro­aniline, KOH and 4-chloro-1-isothio­cyanato­benzene in ethanol solution at room temperature. The structure of the title compound is symmetrical. The molecule lies across a mirror plane. There are some weak C—H⋯S inter­molecular inter­actions in the crystal structure. [ABSTRACT FROM AUTHOR]

The title compound, C14H16N2O2S, was prepared by the reaction of benzaldehyde, ethyl acetoacetate and thio­urea sulfate. There are weak inter­molecular hydrogen-bond inter­actions in the crystal structure, involving the amine and thio­ketone groups as donors and acceptors, respectively. [ABSTRACT FROM AUTHOR]

The title compound, C11H15NOS, was prepared by the reaction of phenyl isothio­cyanate with isobutyl alcohol at room temperature. The central CNC(=S)O group is essentially planar. In the crystal structure, the mol­ecules are connected via N—H⋯S inter­actions. [ABSTRACT FROM AUTHOR]
