Reference of 16532-79-9, 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. 16532-79-9, name is 4-Bromophenylacetonitrile belongs to nitriles-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below.
Step 2: Preparation of l-(4-bromophenyl)cyclopropanecarbonitrile; To a room temperature solution of 4-bromophenylacetonitrile ( 18.0 g) in a solution of 22 mL of sodium hydroxide (50% in water WAV) were added l-bromo-2-chloroethane and (12.0 mL) and benzyltriethylammonium chloride (627 mg). The mixture was heated at 600C overnight. The reaction mixture was cooled to room temperature and diethyl ether was added (300 mL) and partitioned. The ether layer was washed with water (100 mL), hydrogen chloride (100 mL, 10% HCl in water), brine and dried with magnesium sulfate. Upon removal of the solvent in vacuo, the residue was purified by swish using diethyl ether and hexanes to yield the title compound.1H NMR (CD3COCD3) delta 7.60 (2 H, d), 7.35 (2 H, d), 1.74-1.80 (2 H, m), 1.52-1.57 (2 H, m).
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, 4-Bromophenylacetonitrile, other downstream synthetic routes, hurry up and to see.
