1-Acetyl-5-isobutyl-2-sulfanylideneimidazolidin-4-one
There are two independent mol-ecules in the asymmetric unit of the title compound, C(9)H(14)N(2)O(2)S. In the crystal, the mol-ecules are linked by N-H⋯O hydrogen bonds, forming a chain along the a axis.

In the title compound, C(20)H(19)FN(2)O(2), the dihedral angle between the aromatic rings is 62.1 (1)°, and those between the pyrazole ring and the fluoro-benzene and benzoic acid rings are 52.1 (1) and 53.1 (1)°, respectively. In the crystal, mol-ecules are linked into [010] C(7) chains by O-H⋯N hydrogen bonds.
متن کامل2-Isobutyl-2-phosphabicyclo[3.3.1]nonane 2-selenide
The title compound, C(12)H(23)PSe, represents the first structure of a phosphine containing the bicyclic 2-phospha-bicyclo-[3.3.1]nonane (VCH) unit. It contains two chiral centres per mol-ecule which can be either R,R- or S,S and crystallizes as a centrosymmetric, racemic micture of the enanti-omers. The P-Se bond distance of 2.1360 (16) Å is typical for these compounds. The Tolman cone angle (...
متن کاملN-[4-Acetyl-5-isobutyl-5-(2-p-tolylpropyl)-4,5-dihydro-1,3,4-thiadiazol-2-yl]acetamide ethyl acetate hemisolvate
The racemic title compound, a new terpenoid, C(20)H(29)N(3)O(2)S·0.5C(4)H(8)O(2), was synthesized from Cedrus Atlantica essential oil. The compound crystallizes with a disordered ethyl acetate solvent mol-ecule. The thia-diazole ring is almost planar, with a maximum deviation from the mean plane of 0.015 (2) Å for the C atom connected to the isobutyl group and has a puckering amplitude of 0.026...
متن کاملDissolution of isobutyl 2-cyanoacrylate on long-term follow-up.
Eight patients with arteriovenous malformations (AVMs) in the basal ganglionic and deep parietooccipital regions and one patient with an AVM in the shoulder region showed resorption of the isobutyl 2-cyanoacrylate cast and recanalization of the arteries after delayed follow-up angiography. All the AVMs were large, had multiple arterial pedicles, and revealed significant obliteration of the AVM ...
