Synthetic Route of 2132-62-9, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 2132-62-9, name is 1,2-Bis(4-methoxyphenyl)ethyne belongs to ethers-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below.
Example 5 Preparation of 3,4-Bis(4-methoxyphenyl)-1-ethoxybenz[c-1,2]oxaphosphinine 1-oxide 3,4-Bis(4-methoxyphenyl)-1-ethoxybenz[c-1,2]oxaphosphinine 1-oxide (57.0 mg, 90%) as a target compound was obtained under the condition of 90 C. for 12 hours, by the same reaction as the Example 1 above, except for using 1,2-bis(4-methoxyphenyl)ethyne (54.0 mg, 0.23 mmol) instead of using diphenylacetylene of the Example 1 above. 1H NMR (400 MHz, CDCl3) delta 7.95-7.89 (m, 1H), 7.48-7.43 (m, 1H), 7.41-7.37 (m, 1H), 7.19 (dt, J=9.17 Hz, 2.56 Hz, 2H), 7.14-7.10 (m, 2H), 7.00-6.96 (m, 1H), 6.93-6.89 (m, 2H), 7.19 (dt, J=9.20 Hz, 2.52 Hz, 2H), 4.30-4.15 (m, 2H), 3.84 (s, 3H), 3.75 (s, 3H), 1.31 (t, J=4.82 Hz, 3H)
The synthetic route of 1,2-Bis(4-methoxyphenyl)ethyne has been constantly updated, and we look forward to future research findings.
