2-Diazo-1-(1,1-dioxothiomorpholin-4-yl)ethanone
In the mol-ecule of the title compound, C(6)H(9)N(3)O(3)S, at 105 K, the six-membered ring is predominantly found in the chair conformation, with 1.89 (14)% in the boat conformation. In the crystal structure, there are five inter-molecular C-H⋯O=C and C-H⋯O=S contacts less than 2.6 Å, as well as a weak C-H⋯N=N inter-action to the diazo group.

In the title compound, C(10)H(11)ClO(3), obtained by the reaction of 2,4-dihy-droxy-acetophenone, potassium carbonate and 1-bromo-2-chloro-ethane, an intra-molecular O-H⋯O hydrogen bond occurs.
متن کامل1-(Furan-2-yl)-2-(2H-indazol-2-yl)ethanone
The asymmetric unit of the title compound, C13H10N2O2, contains two crystallographically independent mol-ecules (A and B). The indazole ring systems are approximately planar [maximum deviations = 0.0037 (15) and -0.0198 (15) Å], and their mean planes are oriented at 80.10 (5) and 65.97 (4)° with respect to the furan rings in mol-ecules A and B, respectively. In the crystal, pairs of C-H⋯N hydro...
متن کامل1-[2-(Trityloxy)phenyl]ethanone
In the title compound, C27H22O2, the acetyl group is nearly coplanar with the the ring to which it attacted [O-C-C-C torsion angle = -5.5 (3)°]. The three phenyl groups of the tri-phenyl-methyl substituent are mutually nearly perpendicular, making dihedral angles of 89.87 (11) and 78.29 (11) and 60.34 (11)°. Two intra-molecular C-H⋯ O hydrogen bonds occur. In the crystal, C-H⋯ O hydrogen bonds ...
