HPLC of Formula: 707-61-9. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: 4-Methyl-1-phenyl-2,3-dihydro-1H-phosphole 1-oxide, is researched, Molecular C11H13OP, CAS is 707-61-9, about Catalytic aza-Wittig Cyclizations for Heteroaromatic Synthesis. Author is Marsden, Stephen P.; McGonagle, Alison E.; McKeever-Abbas, Ben.
The first examples of heterocycle synthesis by iminophosphorane formation/intramol. aza-Wittig cyclizations that are catalytic in the organophosphorus component are reported. The reaction has been demonstrated in the synthesis of both azine (phenanthridine) and azole (benzoxazole) heterocycles. E.g., in presence of phospholene oxide I, reaction of isocyanate 2-OCNC6H4C6H4CO2Me-2, formed from acyl azide 2-N3COC6H4C6H4CO2Me-2 by Curtius rearrangement, gave 71% phenanthridine II. Catalyst loadings down to 1 mol % have been used with little or no loss in reaction efficiency. The intimate involvement of the phosphine oxide in the catalytic cycle has been verified by in situ IR spectroscopy.
This literature about this compound(707-61-9)HPLC of Formula: 707-61-9has given us a lot of inspiration, and I hope that the research on this compound(4-Methyl-1-phenyl-2,3-dihydro-1H-phosphole 1-oxide) can be further advanced. Maybe we can get more compounds in a similar way.
