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 NMR and uv spectral studies of some 1-aryl-substituted 3-methyl-2-phospholene oxides, the main research direction is phospholene aryl oxide NMR UV.Safety of 4-Methyl-1-phenyl-2,3-dihydro-1H-phosphole 1-oxide.
The NMR and uv spectra of 7 1-aryl-3-methyl-2-phospholene oxides (I, R = H, Me, NMe2, etc.) are discussed. The value of 25 cps for the coupling constants of the P atom with vinylic protons indicates a Δ2,3 position of the phospholene ring double bond. The linear correlation of the bathochromic shift values with substituent constants (σ°) shows a low conjugative interaction between the benzene ring and the phosphoryl group.
