studied. The preparative results, the thermal stability of the photochemical substrate, and the limiting quantum yield values obtained from photoreactions with several nucleophiles suggest the possible usefulness of 2-fluoro-4-nitrophenyl ethers as biochemicalphotoprobes.
photosubstitutions of 2-fluoro-4-nitroanisole with several amines are studied from the preparative and the preliminary mechanistic points of view. The possible usefulness of this structure as biochemicalphotoprobe is discussed.
The photoreactions of nitrophenyl ethers with simple primary and secondary amines show a remarkable nucleophile influence on the reaction orientation. Calculations indicate a change from charge controlled to frontier orbital controlled reactions moving from smaller to larger amines.
