Related Products of 2789-89-1, 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. 2789-89-1, name is 1,2-Bis(4-bromophenyl)ethyne belongs to bromides-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below.
A small molecule luminescent material (P37) based on 1,2-diphenylacetylene as the acceptor unit,The specific steps are:Under nitrogen protection,To a three-necked flask was added 100 ml of toluene,1 g of intermediate 1 (2.99 mmol),2.14 g of 9-phenyl-3-carbazole boronic acid (7.45 mmol, 2.5 equ)Under stirring, 3.47 g of sodium tert-butyl alcohol was added,Then add 230 mg of palladium acetate,0.5 mL of tri-tert-butylphosphine,90 & lt; 0 & gt; C overnight.Cooling, extraction of organic phase with methylene chloride, spin dry,Column. To give 1.48 g of product as a yellow solid in 75% yield.
The synthetic route of 1,2-Bis(4-bromophenyl)ethyne has been constantly updated, and we look forward to future research findings.
