, p. 269 - 273 (2013)
The Schiff base thiophenyl-2-methylidene-2-aminophenol (ImineOH) is obtained from a stoichiometric mixture of 2-thiophenecarboxaldehyde and 2-aminophenol in ethanol under reflux at 90 C. Its crystal structure is determined by single crystal X-ray diffract

Paragraph 0207 - 0209, (2016/10/07)
In OLEDs, improved efficiency is obtained by compounds which can form inter alia electron injection layers of the formula (I) wherein R1 is a 1-5 ring aryl (including polycyclic), aralkyl or heteroaryl group which is optionally substituted with one or mor
Highly enantioselective imine cinnamylation with a remarkable diastereochemical switch
Huber, John D.,Leighton, James L.
, p. 14552 - 14553 (2008/09/19)
The first general method for the enantioselective cinnamylation of aldimines is reported. The method utilizes a simple chiral cinnamylsilane reagent and is characterized by experimental simplicity and extraordinarily high levels of enantioselectivity. Fur

The synthesis of Zn, Cd and Ni complexes of Schiff bases 2-(o-hydroxyphenyliminomethyl)thiophene and 2-(o-hydroxyphenyliminomethyl)pyrrole is described.The nature, composition and structure of the isolated solid complexes have been elucidated by elemental
Photochemical and Thermal Reactions of Aromatic Schiff Bases
Tauer, Erich,Grellmann, Karl H.
, p. 4252 - 4258 (2007/10/02)
The photochemical and thermal reactions of aromatic Schiff bases (SB) prepared from o-aminophenol and aldehydes and from o-aminophenol and ketones are compared.All SB's are converted by light into the corresponding benzoxazolines.For the SB's derived from aldehydes, benzoxazoline formation is a prerequisite to convert them by a second photon into benzoxazoles.In some cases oxygen is not required for this second reaction step.SB's derived from ketones are converted into benzoxazoles by the absorption of just one photon, but only in the presence of oxygen and only if the aliphatic residue R1 of the N=C(R1R2) bridge contains at least two carbon atoms.A radical mechanism is proposed for this reaction.Benzoxazine formation is observed in some cases as a thermal side reaction.The photochemical reactions of the latter were also investigated.
