WebNext, 20 mL of boron trifluoride diethyl ether complex was added, and the mixture was kept stirring for additional 6 h. The resulting mixture was filtered, and the solid was washed with diethyl ether and then vacuum-dried for 12 h at 20 °C to obtain 5.02 g (7.93 mmol, yield: 99%) of cobalt complex as a brown solid. Unlike the aluminium and gallium trihalides, the boron trihalides are all monomeric. They undergo rapid halide exchange reactions: BF3 + BCl3 → BF2Cl + BCl2F Because of the facility of this exchange process, the mixed halides cannot be obtained in pure form. WebAn efficient, simple, and practical method has been developed to regioselectively synthesize (E)-stilbenes and (E,E)-1,4-diphenylbuta-1,3-diene in good to excellent yields in the … doma nazivo
