The chemical properties of alicyclic heterocycles are similar to those of the corresponding chain compounds. Compound: 4-Methyl-1-phenyl-2,3-dihydro-1H-phosphole 1-oxide, is researched, Molecular C11H13OP, CAS is 707-61-9, about Organophosphorus-catalyzed diaza-Wittig reaction: application to the synthesis of pyridazines, the main research direction is pyridazine preparation organophosphorus catalyst diaza Wittig.Safety of 4-Methyl-1-phenyl-2,3-dihydro-1H-phosphole 1-oxide.
The elaboration of the first organophosphorus-catalyzed diaza-Wittig reaction is reported. This catalytic reaction is applied to the synthesis of substituted pyridazine I (R1 = H, Me; R2 = Et, Ph, Cy, p-OMe-C6H4, o-F-C6H4, iPr, thiophenyl) and phthalazine derivatives bearing electron-withdrawing groups (R3 = CO2Me, COPh, SO2Ph) with good to excellent yields from substrates containing a diazo functionality II as the starting material and a phospholene oxide as the catalyst.
