The article was titled 《Photoinduced Phosphorylation/Cyclization of Cyanoaromatics for Divergent Access to Mono- and Diphosphorylated Polyheterocycles》.Category: pyridine-derivatives The article contains the following contents:
The visible-light-driven switchable phosphorylation of cyanoaroms. with the 1,6-enyne moiety for the diverse and selective synthesis of phosphorylated polyheterocycles, including phosphorylated aminophosphonates, iminophosphonates, and ketones, was described. Importantly, these photocatalytic transformations feature good functional group tolerance and high regio- and chemoselectivities under mild reaction conditions. These findings might stimulate the exploration of new photocatalytic uses of P(O)-H compounds by employing CN-containing substrates as the radical acceptors. In addition to this study using fac-Tris(2-phenylpyridine)iridium, there are many other studies that have used fac-Tris(2-phenylpyridine)iridium(cas: 94928-86-6Category: pyridine-derivatives) was used in this study.
fac-Tris(2-phenylpyridine)iridium(cas: 94928-86-6) 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. Category: pyridine-derivatives
