YieldReaction ConditionsOperation in experiment
78% With iodine; oxygen; In dimethyl sulfoxide; at 90℃;Green chemistry; 2-Aminobenzohydrazide (76mg, 0.5mmol), 2-(phenylethynyl)benzaldehyde (103mg, 0.5mmol), I2 (25mg, 0.1mmol) were added to a dry reaction flask with high vacuum valve. After three times in vacuum and replacement of oxygen, DMSO (5.0mL) was injected into the mixture. Before reaching completion, the reaction mixture was stirred and heated at 90C under an O2 balloon. The mixture was poured into 50mL water, and the yellow precipitate was formed and collected by filtration. The crude product was purified by chromatography over silica gel to give 3a using ethyl acetate and petroleum ether (1:5) as an eluent.
