Silica-supported boron trifluoride (BF3-SiO2), an efficient, environment friendly and recyclable catalyst for the one-pot synthesis of 4(3H)-quinazolinones was written by Wu, Liqiang;Ma, Weiwei;Yang, Limin;Yan, Fulin. And the article was included in Asian Journal of Chemistry in 2010.Application In Synthesis of 3,4-Dibromoaniline This article mentions the following:
A simple and efficient synthesis of 4(3H)-quinazolinones was accomplished by the one-pot condensation of anthranilic acid, tri-Et orthoformate and primary amines under solvent-free conditions in the presence of BF3-SiO2. In the experiment, the researchers used many compounds, for example, 3,4-Dibromoaniline (cas: 615-55-4Application In Synthesis of 3,4-Dibromoaniline).
3,4-Dibromoaniline (cas: 615-55-4) belongs to organobromine compounds. A variety of minor organobromine compounds are found in nature, but none are biosynthesized or required by mammals. Organobromine compounds have fallen under increased scrutiny for their environmental impact. When the molecular ion is detected, the bromine and chlorine isotope patterns are very distinct, but caution is to be exercised for certain mixed chlorinated/brominated compounds, which can look similar to homohalogen patterns.Application In Synthesis of 3,4-Dibromoaniline
