Crystal structure of N-[3-(benzo[d]thiazol-2-yl)-6-bromo-2H-chromen-2-ylidene]-4-methylbenzenamine
The title compound, C23H15BrN2OS, was the unexpected product in an attempted synthesis of the isomeric 3-(benzo[d]thiazol-2-yl)-6-bromo-1-p-tolylquinolin-2(1H)-one. The Cchromene=N—C angle is wide [125.28 (8)°].

Imine-Enamine Tautomerism -Nucleophilic Reactions of Imines [PDF]
Abstract A reinvestigation of the reactivity of N-isopropylidene cyclohexylamine to methyl acrylate by GC-MS analysis has shown that the major product is the β-aminoester (9) formed by the N-alkylation of cyclohexylamine which may be generated by a dimerisation-elimination sequence.
