5-Hydroxy-7-phenyl-5-(prop-2-yn-1-yl)-5,6-dihydro-1-benzofuran-2(4H)-one monohydrate
In the title compound, C(17)H(14)O(3)·H(2)O, the six-membered ring, which adopts a half-chair conformation, makes a dihedral angle of 24.3 (2)° with the phenyl ring. In the crystal, the components are linked by O-H⋯O hydrogen bonds involving the water mol-ecule, and the hy-droxy and carbonyl groups of the organic compound. These inter-actions form a square-like supra-molecular synthon unit whic...

The title co-crystal, 0.95C(20)H(20)O(3)·0.05C(20)H(19)ClO(3), arises as the chloride carried over during the synthesis shares a position with an aromatic H atom; the partial occupancies are 0.947 (2) and 0.053 (2) for H and Cl, respectively. The mol-ecular structure is stabilized by intra-molecular C-H⋯O contacts, forming pseudo five- and six-membered rings with S(5) and S(6) graph-set motifs,...

4-Phenyl-1H-1,5-benzodiazepin-2(3H)-one reacts in the pres-ence of a concentrated aqueous solution of sodium hydroxide and a quaternary ammonium salt (as catalyst) in benzene (phase transfer catalysis) with propargyl bromide, affording the title benzodiazepine derivative, C(18)H(14)N(2)O. In the mol-ecule, the mean plane of the propargyl substituent is almost perpendicular with that of the amid...

The asymmetric unit of the title compound, C(17)H(14)O(4), contains two independent mol-ecules which differ in the relative orientations of the phenyl rings with repect to the essentially planar [maximum deviations of 0.029 (2) and 0.050 (2) Å in the two mol-ecules] chromene fused-ring system, forming dihedral angles of 10.3 (5) and 30.86 (5)° in the two mol-ecules. The crystal structure is sta...
