Syntheses and Structure of 8-, 7-, and 6-Membered Silacycloallenes
Decreasing the ring size of a cyclic allene to rings of fewer than 10 carbons results in deviation of both the normal C=C=C linearity and the orthogonality of the dihedral angle.' To date, the smallest isolable cycloallene is 1-tert-butyl-1,2-cyclooctadiene,2 and the smallest for which structural information is available is the phenylurethane derivative of cyclonona-2,3-dien-1-oJ,l which is ben...
متن کامل8-(Diphenylphosphanyl)quinoline
The title compound, C(21)H(16)NP, is a known P-N chelator and various crystal structures of its metal complexes have been reported. However, no crystallographic evidence of the free ligand has been given to date. The phenyl rings are almost orthogonal to one another [dihedral angle = 88.9 (1)°], and they are twisted from the mean plane of the quinoline by 80.5 (1) and 76.3 (1)°.
متن کامل8-(4-Nitrobenzyloxy)quinoline
In the title compound, C(16)H(12)N(2)O(3), the planar quinoline ring system [maximum deviation = 0.025 (3) Å] is oriented at a dihedral angle of 61.76 (7)° with respect to the benzene ring. In the crystal structure, inter-molecular C-H⋯O inter-actions link the mol-ecules into chains parallel to the b axis. π-π contacts between the quinoline rings [centroid-centroid distance = 3.623 (1) Å] may f...
متن کاملQuinoline-8-sulfonamide1
In the title compound, C(9)H(8)N(2)O(2)S, the sulfamoyl NH(2) group is involved in intra-molecular N-H⋯N and inter-molecular N-H⋯O hydrogen bonding. In the crystal, molecules are linked via pairs of N-H⋯O hydrogen bonds, forming inversion dimers, which are further associated through π-π stacking inter-actions between the quinoline benzene rings [centroid-centroid distance = 3.649 (1) Å] into a ...
متن کامل8-(Naphthalen-1-yl)quinoline
In the title mol-ecule, C(19)H(13)N, the angle between the mean planes of the naphthalene and quinoline ring systems is 68.59 (2)°. The compound is of inter-est with respect to its potential for spontaneous resolution. In the crystal structure, the R and S isomers are arranged in alternating homochiral layers. The mol-ecules of a given layer are oriented with their major axes (i.e. the axis per...
