2-[(2-Bromo-phen-yl)imino-meth-yl]-6-methyl-phenol.

In the title compound, C(14)H(12)BrNO, is a Schiff base which adopts the phenol-imine tautomeric form in the solid state. The dihedral angle between the two aromatic rings is 34.26 (9)° and an intra-molecular O-H⋯N hydrogen bond generates an S(6) ring.

2-[(E)-2-Hy-droxy-5-(trifluoro-meth-oxy)benzyl-idene-amino]-4-methyl-phenol.

The title compound, C(15)H(12)F(3)NO(3), is a Schiff base which adopts the cis-quinoid form in the solid state. The dihedral angle between the least-squares planes of the benzene rings being 3.6 (1)°.

(E)-4-Bromo-2-[(4-ethyl-phen-yl)imino-meth-yl]phenol.

In the title compound, C(15)H(14)BrNO, the dihedral angle between the two benzene rings is 43.99 (2)°. The mol-ecular conformation is influenced by an intra-molecular O-H⋯N hydrogen bond.
