In 2017,Hayashi, Minoru; Nishimura, Yasunobu; Watanabe, Yutaka published 《Syntheses of 3-oxo-λ5-benzophospholes by an intramolecular cyclization of phosphorus-ylide》.Chemistry Letters published the findings.Product Details of 31106-82-8 The information in the text is summarized as follows:
Three synthetic procedures were developed for a new class of P ylide containing conjugate heterocycles, 3-oxo-λ5-benzophospholes. The key to the formation of the heterocycle is unusual intramol. acylation of a P ylide forming an endocyclic ylide. Several types of 2-substituted benzophospholes were synthesized, some of which show fluorescence. After reading the article, we found that the author used 2-(Bromomethyl)pyridine hydrobromide(cas: 31106-82-8Product Details of 31106-82-8)
2-(Bromomethyl)pyridine hydrobromide(cas: 31106-82-8) belongs to pyridine. Pyridine is very deactivated towards electrophilic substitution with respect to benzene. For this reason classical formylation, using methods such as the Gattermann or Vilsmeier reactions, are not generally successful. Product Details of 31106-82-8
