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. 33170-72-8, name is 2-Bromo-1,1-dimethoxypropane belongs to ethers-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below. Product Details of 33170-72-8
Step 1: (1,1-Dimethoxypropan-2-yl)hydrazine 6.25 g (34.1 mmol) of 2-bromo-1,1-dimethoxypropane and 6.65 ml (137 mmol) of hydrazine hydrate were stirred under reflux in an oil bath at 140 C. for 6 h. After cooling, the two-phase reaction mixture was extracted with 50 ml of tert-butyl methyl ether. The organic phase was filtered, the filtrate was concentrated on a rotary evaporator and the residue was dried under high vacuum. This gave 1.89 g (21% of theory) of a pale yellow oil which was reacted directly, without further purification, in the subsequent reaction.
The synthetic route of 33170-72-8 has been constantly updated, and we look forward to future research findings.
