Application of 13440-07-8, An article , which mentions 13440-07-8, molecular formula is C20H15OP. The compound – Di(naphthalen-1-yl)phosphine oxide played an important role in people’s production and life.
A novel and efficient method for the generation of phosphinoyl radicals from the combination of diphenyliodonium salt (Ph2I+,-OTf) with triethylamine (Et3N) in the presence of secondary phosphine oxides is reported. By employing this practical and simple approach, a large variety of 6-phosphorylated phenanthridines have been synthesized through the addition of phosphinoyl radicals to isonitriles as radical acceptors. The reaction works smoothly in the absence of any transition metal or photocatalyst. On the basis of electron paramagnetic resonance (EPR) and density functional theory (DFT) calculations, the mechanism of this reaction is discussed.
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 13440-07-8, help many people in the next few years., Application of 13440-07-8
