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. 955959-84-9, name is 4-(4-Bromophenyl)dibenzo[b,d]furan, A new synthetic method of this compound is introduced below., HPLC of Formula: C18H11BrO
4(4-bromophenyl)dibenzo[b,d]furan (138 mmol) and 4(9-ethyl-9H-indazol-1-yl)aniline (125.5 mmol) were added to the reaction vessel in that order. After tris(dibenzylideneacetone)dipalladium (6.3 mmol), tri-tert-butylphosphine (12.5 mmol), sodium t-butoxide (376.4 mmol), and toluene 1320 mL, the reaction was carried out at 100 ° C; The organic matter was extracted with diethyl ether and water, and the organic layer was dried over magnesium sulfate. Intermediate 1, 94.13 mmol (75percent), mass spectrum: theoretical 528.24, calculated 528.20;
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.
