Reference of 28148-04-1, 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. 28148-04-1, name is 1,3-Dibromo-2-methylpropane belongs to bromides-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below.
The beta- lactam carbonyl compound of the formula shown in C6H5-COCH2CONH-CH31.0mmol added 50 ml round bottomFlask, and then followed by adding K2CO32.4mmol, tetrabutylammonium bromide 0.07mmol, ammonium acetate 1.2mmol, 1,3- dibromo-2-Methyl propane 1.2mmol and 30mL of deionized water and mix well. The reaction was continued stirring at 30 deg C 8.0 hours, stoppedThe reaction, was filtered, dried, purified by recrystallization methanamine obtained after 5-benzoyl-6- methyl-3,4-dihydro-pyran-3, 87% yield of product.
The synthetic route of 1,3-Dibromo-2-methylpropane has been constantly updated, and we look forward to future research findings.
