Related Products of 955959-84-9, The chemical industry reduces the impact on the environment during synthesis 955959-84-9, name is 4-(4-Bromophenyl)dibenzo[b,d]furan, I believe this compound will play a more active role in future production and life.
Intermediate M-1 15g (46.4mmol) in a round bottom flask and 9,9-Dimethyl-9H-fluoren-2-ylamine 4.8g (23.2mmol),sodium-t- butoxide 6.7g (69.6mmol) ofIt was dissolved in toluene into a 185ml. Here Pd (dba) 2 0.53g (0.928mmol) and tri-tert-butylphosphine was placed to 0.38g (1.86mmol) in turn and the mixture was stirred under reflux for 4 hours under a nitrogen atmosphere. After completion of the reaction and then extracted with toluene the organic layer was dried and distilled over magnesium sulfate, filtered and the filtrate was concentrated under reduced pressure. The product n- hexane / dichloromethane (8: 2 by volume) to give compound 8 as a purification by a silica gel column chromatography as a white solid 14.4g (90percent yield).
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 4-(4-Bromophenyl)dibenzo[b,d]furan, other downstream synthetic routes, hurry up and to see.
