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. 18869-30-2, name is (E)-1,2-Bis(4-bromophenyl)ethene belongs to bromides-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below. 18869-30-2
EXAMPLE 3 Ethyl 4-bromostilbene-4′-acrylate. 25.8 g (0.1 mol) of 4,4′-dibromostilbene, 10 g (0.1 mol) of ethyl acrylate, 18.5 g (0.1 mol) of tri-n-butylamine, 0.224 g (0.001 mol) of palladium acetate and 0.6 g (0.002 mol) of tri-o-tolylphosphine are added under argon to 50 ml of p-xylene. The reaction mixture is stirred at 90 C. for 4 hours. Working up gives 2 g (6% of theory) of ethyl 4-bromostilbene-4′-acrylate. Melting point 166.9 C.
The synthetic route of 18869-30-2 has been constantly updated, and we look forward to future research findings.
