tert - Butyl 3 - ( 4 - Cyano - 5 - phenylisothiazol - 3 - yl ) carbazate
3-Iodo-5-phenylisothiazole-4-carbonitrile 1 reacts with tert-butyl carbazate via a Buchwald C-N style coupling to afford tert-butyl 3-(4-cyano-5-phenylisothiazol-3-yl)carbazate 2 in 70% yield.
متن کامل3-Bromo-5-tert-butyl-2-hydroxybenzaldehyde
The mol-ecular conformation of the title compound, C(11)H(13)BrO(2), is stabilized by an intra-molecular O-H⋯O hydrogen bond. All non-H atoms except the methyl groups lie approximately in a common plane (r.m.s. deviation = 0.011 Å).

In the title compound, C(13)H(16)N(4)O(2), the pyrazole ring forms a dihedral angle of 50.61 (6)° with the 3-nitro-phenyl ring. The plane of the nitro group is twisted by 6.8 (7)° out of the plane of the phenyl ring. In the crystal, the mol-ecules are linked by N-H⋯N and N-H⋯O hydrogen bonds, forming sheets in the bc plane. In addition, a weak C-H⋯N inter-action is observed.

The title compound, C17H29NO4, contains a chiral center and crystallizes as a racemate. The asymmetric unit consists of two non-equivalent mol-ecules, in which the carbeth-oxy groups have markedly different orientations [C(=O)CC(OEt)=O torsion angles = 59.3 (2) and 156.0 (2)°]. In the crystal, mol-ecules form chains along [101] through N-H⋯O hydrogen bonds.
متن کامل5-tert-Butyl-2-hydroxy-3-(2-thienyl)benzaldehyde
In the crystal structure of the title compound, C(15)H(16)O(2)S, the thio-phene ring is essentially planar (r.m.s. deviation = 0.006 Å for all non-H atoms) and roughly coplanar with the benzene ring, the dihedral angle between the mean planes of the rings being 4.35 (8)°. An intra-molecular O-H⋯O hydrogen bond is observed between the OH group and the aldehyde O atom.
