Ethyl 2-(3,5-dimethyl-1,1-dioxo-2H-1λ6,2,6-thiadiazin-4-yl)benzoate
In the title compound, C(14)H(16)N(2)O(4)S, the thia-diazine ring is in a half-boat conformation. The aromatic ring deviates from the plane of this moiety at an angle of 74.6 (2)°. The structure displays inter-molecular N-H⋯O hydrogen bonding [N⋯O = 2.8157 (16) Å], creating ribbons along the [010] axis. There are also weak C-H⋯O inter-actions in the crystal but no π-π stacking.

In the title compound, C(18)H(20)N(2)O(5), the pyrrolidine ring adopts an envelope conformation with the C atom bonded to the methyl groups as the flap. The dihydro-isoxazole ring is essentially planar (r.m.s. deviation = 0.041 Å) and forms a dihedral angle of 65.19 (6)° with the phenyl ring. In the crystal, neighbouring mol-ecules are linked into chains along [110] by inter-molecular C-H⋯O hyd...

In the title mol-ecule, C(15)H(17)N(3)O(4)S, the heterocyclic thia-zine ring adopts a twist-boat conformation, which differs from that in related compounds, with adjacent S and C atoms displaced by 0.981 (4) and 0.413 (5) Å, respectively, on the same side of the mean plane formed by the remaining ring atoms. The mean plane of the benzene ring makes a dihedral angle of 23.43 (14)° with the mean ...
متن کاملSub-Atmospheric Distillation for Water (1) + Dimethyl Amino Ethyl Azide (2) Mixture
Dimethyl amino ethyl azide (DMAZ) is a good replacement for hydrazine group in space programs. This chemical was purified from water (1) + DMAZ (2) mixture in sub-atmospheric distillation column due to thermal sensitivity of DMAZ. For designing of the column, it is necessary to have vapor-liquid equilibrium data. In this article, T-x,y and y-x diagrams were obtain...

In the title compound, C23H22N2O4S, the pyrrolidine ring has an envelope conformation with the spiro C atom, shared with the indoline ring system, as the flap. The mean planes of the benzo-thio-phene and indoline ring systems are inclined to the mean plane of the pyrrolidine ring by 88.81 (8) and 79.48 (8)°, respectively, and to each other by 68.12 (5)°. In the crystal, mol-ecules are linked vi...
