Adding a certain compound to certain chemical reactions, such as: 60876-70-2, name is 1-Bromo-4-(tert-butoxy)benzene, belongs to ethers-buliding-blocks compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 60876-70-2, Quality Control of 1-Bromo-4-(tert-butoxy)benzene
Synthesis of (4-tert-butoxy-phenylethynylVtrimethyl-silane (2). A 20 mL microwave tube was charged with a mixture of 1 -bromo-4-tert- butoxybenzene 1 (1.0 g, 4.36 mmol), PdCl2(dppf) (71 mg, 0.087 mmol), CuI (33 mg,0.174 mmol), DIPA (0.924 mL, 6.55 mmol), and THF (15 mL). Tube was backfilled with nitrogen, sealed, and irradiated in a microwave reactor (max. power 250W) at 100C for 5 min. Solution was diluted with water (200 mL) and extracted with EtOAc (3 x 80 mL). Combined organic layers were washed with water (1 x 100 mL) and brine (1 x 80 mL), dried (Na2SO4), filtered and concentrated in vacuo. Crude product was purified by normal phase flash chromatography (40 g SiO2, 0-30% EtO Ac/Hex) to provide the desired compound 2 (488 mg, 45%) as a clear colorless oil. LC-MS: [M+H]+= Not observed; Ret. Time (Method A) 7.87 min; 1H NMR (250 MHz, CDCl3) delta 0.2 (s, 9H), 1.3 (s, 9H), 6.9 (d, 2H), 7.4 (d, 2H).
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, 1-Bromo-4-(tert-butoxy)benzene, other downstream synthetic routes, hurry up and to see.
