Rate laws may be derived directly from the chemical equations for elementary reactions. This is not the case, however, for ordinary chemical reactions.5-Chloro-3-phenylbenzo[c]isoxazole, cas is 719-64-2,the Benzisoxazole compound, below Introduce a new synthetic route., 719-64-2
(3) 5-Chloro-3-phenyl-2,1 benzisoxazole,Iron powder,The concentration of 95% ethanol,Heat reflux at 35C for 30 minutes,Then, ethanol was added dropwise to the system.among them,The volume ratio of hydrochloric acid to ethanol is 1:5.After refluxing, reflux at 35C for 2 hours.Sodium hydroxide solution was added dropwise to adjust the pH of the system to 7,Add activated carbon to the systemContinue refluxing for 20 minutes,filter,The filter residue is vacuum dried at 50C for 4 hours.among them,5-chloro-3-phenyl-2,1benzoxazole,Iron powder,95% ethanol,Ethanol solution of hydrochloric acid,The mass ratio of activated carbon is 2:1.2:15:2:0.2,That is, 2-amino-5-chlorobenzophenone is obtained.
According to the analysis of related databases, 5-Chloro-3-phenylbenzo[c]isoxazole, the application of this compound in the production field has become more and more popular.
