Molecular photoswitches based on spiro-acridans was written by Raskosova, Alina;Stoesser, Reinhard;Abraham, Werner. And the article was included in Chemical Communications (Cambridge, United Kingdom) in 2013.Application In Synthesis of Ethyl (2-bromophenyl)acetate This article mentions the following:
Thermally reversible photochromic spiro-acridans have been synthesized for the first time. They exhibit high ring opening efficiencies. As the formed zwitterions do not possess a merocyanine structure their lifetime is in the range of milliseconds to seconds. An observed side reaction can be avoided by suitable substitution of hydrogen atoms. In the experiment, the researchers used many compounds, for example, Ethyl (2-bromophenyl)acetate (cas: 2178-24-7Application In Synthesis of Ethyl (2-bromophenyl)acetate).
Ethyl (2-bromophenyl)acetate (cas: 2178-24-7) belongs to organobromine compounds. Bromine is more electronegative than carbon (2.9 vs 2.5). Consequently, the carbon in a carbon–bromine bond is electrophilic, i.e. alkyl bromides are alkylating agents. The principal reactions for organobromides include dehydrobromination, Grignard reactions, reductive coupling, and nucleophilic substitution.Application In Synthesis of Ethyl (2-bromophenyl)acetate
