RESUMO
In the title mol-ecule, C(15)H(13)BrN(2)O(2), an intra-molecular O-Hâ¯N hydrogen bond influences the mol-ecular conformation; the two benzene rings form a dihedral angle of 13.6â (3)°. In the crystal, inter-molecular N-Hâ¯O hydrogen bonds link the mol-ecules into chains along the a axis and weak inter-molecular C-Hâ¯O hydrogen bonds further link these chains into layers parallel to the ac plane.
RESUMO
In the title compound, C(17)H(12)O(4), the chromene unit is approximately planar, the maximum deviation from the mean plane being 0.0166â Å. The attached phenyl ring makes a dihedral angle of 53.2â (1)° with the fused ring system. The packing of the mol-ecules in the crystal structure is governed by C-Hâ¯O and O-Hâ¯O hydrogen-bonding inter-actions.
RESUMO
A novel ruthenium-catalyzed decarboxylative cross-coupling of carbonothioate is disclosed. This method provides straightforward access to the corresponding allyl(aryl)sulfide derivatives in generally good to excellent yields under mild conditions and features a broad substrate scope, wide group tolerance and in particular, no need to use halocarbon precursors.
