Reported here is an intermol. pyridylation/phosphinoylation of alkenes using 4-cyanopyridine and diphenylphosphine oxide under visible-light-induced organic photoredox catalysis. The reaction occurs under mild metal-free conditions, possessing a broad substrate scope. The protocol can be practiced on a gram scale and applied to the modification of natural product-derived and medicinally relevant complex mols. containing a styrene unit. Mechanistic investigations suggest that triethylamine serves as both single-electron transfer (SET) and hydrogen atom transfer (HAT) agents. In the part of experimental materials, we found many familiar compounds, such as 4-Cyanopyridine(cas: 100-48-1Quality Control of 4-Cyanopyridine)
4-Cyanopyridine(cas: 100-48-1) belongs to pyridine. Pyridine is widely used in the precursor to agrochemicals and pharmaceuticals. Also, it is used as an important reagent and organic solvent.Quality Control of 4-Cyanopyridine
