Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 106-39-8, name is 1-Bromo-4-chlorobenzene, A new synthetic method of this compound is introduced below., Application In Synthesis of 1-Bromo-4-chlorobenzene
A flame-dried Schlenk flask was charged with tris(dibenzylideneacetone)palladium (4.6 mg, 0.005 mmol), 1 (4.4 mg, 0.025 mmol) or 6a (11.9 mg, 0.025 mmol), sodium terf-butoxide (134 mg, 1.40 mmol) and toluene (2.0 ml_) under nitrogen. Aryl bromide (1.00 mmol) and amine (1.10 mmol) were added and the resulting red solution heated at 800C with rapid stirring until reaction was complete, as judged by GC analysis. The reaction mixture was allowed to cool to room temperature, diluted with diethyl ether, passed through celite and the solvent removed to leave a yellow solid. Known products were characterised by NMR spectroscopy and mass spectrometry and unknown products by NMR spectroscopy, mass spectrometry and high resolution mass spectrometry (HRMS). The conversions were calculated using GC analysis as an average over three repeats.
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
