3-tert-Butyl-1H-isochromene-1-thione
The title compound, C(13)H(14)OS, crystallizes with two independent mol-ecules in the asymmetric unit. The unit cell contains three voids of 197 Å(3), but the residual electron density (highest peak = 0.24 e Å(-3) and deepest hole = -0.18 e Å(-3)) in the difference Fourier map suggests no solvent mol-ecule occupies this void. The crystal structure is stabilized by π-π inter-actions between the ...
متن کاملHydrogen atom transfer reactions in thiophenol: photogeneration of two new thione isomers.
Photoisomerization reactions of monomeric thiophenol have been investigated for the compound isolated in low-temperature argon matrices. The initial thiophenol population consists exclusively of the thermodynamically most stable thiol form. Phototransformations were induced by irradiation of the matrices with narrowband tunable UV light. Irradiation at λ > 290 nm did not induce any changes in i...
متن کاملReactions of 9H-Fluorene-9-thione with (Trimethylsilyl)- diazomethane*
The [3+2]-cycloaddition of (trimethylsilyl)diazomethane (7) with 9H-fluorene-9-thione (1) at –60°C yields the spirocyclic 2,5-dihydro-5-trimethylsilyl-1,3,4-thiadiazole 10, which eliminates nitrogen at room temperature to give the 1,4-dithiane derivative 13 by dimerization of the intermediate fluorenethione (trimethylsilyl)methanide (11). This thiocarbonyl ylide can be trapped by 1 to give the ...
متن کامل(S)-N-Phenyl-tert-butanesulfinamide
The asymmetric unit of the title compound, C(10)H(15)NOS, contains two independent mol-ecules with similar conformations. In the crystal, mol-ecules are linked in a head-to-tail fashion by N-H⋯O hydrogen bonds into chains running along the b axis. The absolute configuration was assigned on the basis of known chirality of the parent compound.
