Reference of 1579-40-4, The chemical industry reduces the impact on the environment during synthesis 1579-40-4, name is Di-p-tolyl Ether, I believe this compound will play a more active role in future production and life.
Prior to use, NBS was recrystallized from water and the carbon tetrachloride was bubbled with nitrogen, stirred for 45 min with sodium sulfate, and checked by 1H-NMR spectroscopy. To a stirred solution of 4,4′-oxybis(methylbenzene) (28) (5.0 g, 25.2 mmol, 1 eq.) and NBS (8.98 g, 50.4 mmol, 2 eq.) in carbon tetrachloride (125 mL) under nitrogen was added a catalytic amount of AIBN. The reaction mixture was heated to 80-90 C (reflux) and stirred for 6.5 h. The solution was then cooled and the succinimide was removed on a sintered glass filter funnel. The solvent was removed in vacuo to yield the desired product 29 as beige crystals (8.3 g, 93%). A portion (1.82 g) was purified by flash chromatography (10:1 hexane:EtOAc) to yield 29 as white crystals: mp 85-86 C (lit.29 mp 93-95 C). 1H NMR (CDCl3): delta 7.38 (d, 4H), 6.98 (d, 4H), 4.52 (s, 4H).
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, Di-p-tolyl Ether, other downstream synthetic routes, hurry up and to see.
