1,1′-(Phenylmethylene)dinaphthalen-2-ol
نویسنده
چکیده
In the title compound, C(27)H(20)O(2), the phenyl ring is oriented with respect to the naphthalene ring systems at 57.87 (6) and 85.12 (6)°. The two naphthalene ring systems make a dihedral angle of 70.10 (4)°. In the mol-ecule, the hy-droxy groups are involved in a strong intra-molecular O-H⋯O hydrogen bond. In the crystal, inversion dimers linked by pairs of O-H⋯O hydrogen bonds occur. A weak C-H⋯π inter-action is also observed in the crystal.

In the solid state the title Schiff base, 0.58C(28)H(20)N(2)O(2)·0.42C(28)H(20)N(2)O(2), exists both as the keto-imino and as the enol-amino tautomer, which is manifested in the disorder of the H atom in the intra-molecular hydrogen-bonded ring. The naphthalene ring systems show some distortion, which is consistent with the quinoid effect. The ratio of the enol form refined to 58 (5)%. The mol-...

The title compound, C(37)H(26)N(2)O(2), was synthesized from 1,1'-methyl-enedinaphthalen-2-ol and 3-(bromo-methyl)-benzo-nitrile. The two naphthyl systems are almost perpendicular to each other [dihedral angle 83.3 (9)°] and the two cyano-benz-yloxy rings approximately parallel to each other [dihedral angle 15.5 (2)°].

Propargyl alcohol is a useful synthon in synthetic organic chemistry. We found that the ruthenium(II) complex [Cp*RuCl(diene)] (Cp* = η-C5Me5; diene = isoprene or 1,5-cyclooctadiene (cod)) catalyzes dimerization of 1,1-diphenylprop-2-yn-1-ol (1,1-diphenylpropargyl alcohol, 1a) at room temperature to afford an alkylidenebenzocyclobutenyl alcohol 2a quantitatively. Meanwhile, a stoichiometric rea...

The title compound, C(35)H(35)NO(2)·CH(4)O, was obtained by the reaction of rac-2-amino-2-hy-droxy-1,1-binaphthyl and 3,5-di-tert-butyl-2-hy-droxy-benzaldehyde in absolute methanol. In the Schiff base mol-ecule, the two naphthyl bicycles are twisted by 71.15 (5)°. One hy-droxy group is involved in intra-molecular O-H⋯N hydrogen bond, while the methanol solvent mol-ecule is linked to another hy-...
