Photochemical Synthesis of Phenanthridines: Exploring Fluoro and Protected Catechol Substitution was written by Linsenmeier, Anna M.;Williams, Craig M.;Brase, Stefan. And the article was included in European Journal of Organic Chemistry in 2013.Formula: C7H5Br2F This article mentions the following:
Substituted phenanthridines, such as the natural product trispheridine, have been accessed by the practical photochem. cyclization of N-benzylanilines. Functionalities, with a focus on fluoro substituents and protected catechols, are well tolerated on both the A and C rings. The phenanthridines were accessed in good to very good yields (up to 95 %) from iodinated substrates, whereas brominated substrates performed poorly in comparison (0-48 %). In the experiment, the researchers used many compounds, for example, 2-Bromo-4-fluorobenzylbromide (cas: 61150-57-0Formula: C7H5Br2F).
2-Bromo-4-fluorobenzylbromide (cas: 61150-57-0) 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. One prominent application of synthetic organobromine compounds is the use of polybrominated diphenyl ethers as fire-retardants, and in fact fire-retardant manufacture is currently the major industrial use of the element bromine.Formula: C7H5Br2F
