Electric Literature of 2132-62-9, The chemical industry reduces the impact on the environment during synthesis 2132-62-9, name is 1,2-Bis(4-methoxyphenyl)ethyne, I believe this compound will play a more active role in future production and life.
6-chloro-1-(4-chlorophenyl)-3,4-bis(4-methoxyphenyl)-1H-2,1-benzoxaphosphinine 1-oxide (69.1 mg, 88%) as a target product was obtained under the condition of 90 C. for 16 hours, by the same reaction as the Example 1 above, except for using bis(4-chlorophenyl)phosphinic acid (43.0 mg, 0.15 mmol) instead of using phenylphosphonic monoethyl ester of the Example 1 above, and using 1,2-bis(4-methoxyphenyl)ethyne (53.6 mg, 0.23 mmol) instead of using diphenylacetylene of the Example 1 above. (0218) 1H NMR (400 MHz, CDCl3) delta 7.87-7.81 (m, 2H), 7.52-7.44 (m, 3H), 7.29 (td, J=8.1, 2.1 Hz, 1H), 7.17-7.14 (m, 4H), 7.05 (dd, J=4.1, 4.8 Hz, 1H), 6.95 (app d, J=8.7, 2H), 6.67-6.63 (m, 2H), 3.87 (s, 3H), 3.73 (s, 3H).
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, 1,2-Bis(4-methoxyphenyl)ethyne, other downstream synthetic routes, hurry up and to see.
